⚙️ Calculating True Melt Value: Spot Price vs. Dealer Premiums
Each tab solves a different precious metals problem. This guide walks you through exactly what to enter, what each output means, and how to read the results for real buying, selling, and investment decisions.
“Junk silver” refers to pre-1965 US coins (dimes, quarters, half dollars, dollars) that are 90% silver by composition but have no numismatic premium — they trade purely for their silver content. The term “junk” means no collector value, not low quality.
| Coin | Composition | Silver (ozt) each | Common use case |
|---|---|---|---|
| Mercury / Roosevelt Dime | 90% silver | 0.07234 ozt | Most liquid junk silver |
| Washington Quarter (pre-1965) | 90% silver | 0.18084 ozt | Most common in bags |
| Walking Liberty Half Dollar | 90% silver | 0.36169 ozt | Premium junk, easy to count |
| Kennedy Half (1965–1969) | 40% silver | 0.14792 ozt | Often overlooked in change |
| Morgan / Peace Silver Dollar | 90% silver | 0.77344 ozt | Often has numismatic premium |

💡 The IRS Tax Trap: 28% Collectibles Capital Gains Tax
25 expert tips drawn from real precious metals investor scenarios, IRS guidance, dealer pricing research, and commodity market data. Each tip is mapped to a specific calculator tab so you can apply it immediately.
Fine ozt = (Grams ÷ 31.1035) × Purity%
Example: 18g of 14K = (18÷31.1035)×0.583 = 0.3376 ozt fine gold
Run Tab 1 twice: once at the stamped purity, once at 1 karat lower. The difference shows your downside risk if the stamp is inaccurate.
Get quotes from at least 3 dealers/refineries. Compare each quote to the Tab 1 melt value as a percentage to identify the best offer instantly.
White gold prongs on a ring may be 14K white gold — not the same purity as a yellow gold shank. Weigh components separately if possible.
Override the auto-fetched spot price in Tab 1 with the confirmed spot price your dealer quotes at the exact moment of the transaction to verify their calculation.
Use the PCGS price guide (pcgs.com/prices) to check any unusual date-mint combinations before selling any 90% silver lot for melt.
1964 Kennedy: 0.36169 ozt silver
1965–1970 Kennedy: 0.1479 ozt silver (40% clad)
Difference per coin: 0.2138 ozt = $7.70 at $36/ozt
Check any coin roll or jar of old nickels for the 1942–1945 date range and large mint mark. They look like regular nickels and are easily overlooked.
Run Tab 3 twice — once for the gaining position and once for the losing position. The combined net gain determines your actual collectibles tax liability for the year.
Missing cost basis documentation is one of the top audit triggers for precious metals sales. A $0 cost basis on a $50,000 gold sale means $14,000 in unexpected tax.
CA investor, long-term gold gain $30,000:
Federal: 28% × $30,000 = $8,400
State CA: 9.3% × $30,000 = $2,790
Total tax: $11,190 (37.3% effective)
| Ratio Level | Signal | Historical Frequency |
|---|---|---|
| > 90:1 | Silver extremely cheap | Rare — seen in 2020 |
| 70–90:1 | Silver cheap — accumulate | ~20% of time |
| 50–70:1 | Neutral — hold | ~50% of time |
| 30–50:1 | Gold cheap vs silver | ~25% of time |
| < 30:1 | Swap silver → gold | Rare — seen in 1980 |
Swapping gold for silver at 85:1 sounds smart — but if you pay 20% premium on American Silver Eagles and owe 28% capital gains on the gold, you may need a ratio reversion to 60:1 just to break even.
Enter your total gold value, silver value, platinum/palladium value, and total portfolio value into Tab 4. The output shows your metals percentage and flags it as under-weight, within range, or over-concentrated.
Total fees over 5/10/15/20 years at your custodian’s rate schedule. Fee drag as % of initial investment. Annual gold appreciation needed to exceed fees.
Setup fees, transaction fees per purchase, wire transfer fees, liquidation fees, and account closing fees. The annual numbers in brochures rarely include all of these.
“What is my total all-in annual cost in dollars, not percentages, for a $75,000 account?” Then enter that exact number into Tab 5 for an honest projection.
You are allowed only ONE indirect rollover per 12-month period across ALL your IRAs. A second indirect rollover in the same year is a fully taxable distribution regardless of whether you meet the 60-day window.
The IRS can match bank deposits and cash purchases against unreported precious metals gains. Report all sales regardless of whether you receive a 1099-B.
Name each PDF file: “Metals-Calculation-[DATE]-[METAL]-[PURPOSE].pdf” and store it in the same digital folder as your dealer invoices. Reference the filename in your ledger spreadsheet.

📊 5 Real-World Appraisals (Scrap Jewelry, Bullion Stacks & Coins)
Five real-world scenarios showing exactly what inputs to enter, what results to expect, and what each output means for your specific situation — from scrap jewelry to Gold IRA proposals.
Sarah inherited three gold pieces from her grandmother — a bracelet, a ring, and a chain. A local pawn shop offered her $380 for all three. She didn’t know if that was fair. She ran each piece through Tab 1 before accepting.
| Piece | Hallmark | Weight | Unit | Purity | Fine Gold (ozt) |
|---|---|---|---|---|---|
| Bracelet | 14K (585) | 22.0 g | Gram | 58.5% | 0.4138 ozt |
| Ring | 18K (750) | 7.0 g | Gram | 75.0% | 0.1688 ozt |
| Chain | 10K (417) | 15.0 g | Gram | 41.7% | 0.2011 ozt |
Mike bought a mixed bag of pre-1965 US silver coins for $14,800 at an estate sale. He got a rough count of the coins by type and used Tab 2 to verify the actual silver content and whether he paid a fair premium over melt.
| Coin Type | Qty | Face Value Each | Silver % | ozt Silver Each | Total ozt | Melt Value |
|---|---|---|---|---|---|---|
| Mercury Dimes | 320 | $0.10 | 90% | 0.07234 | 23.15 | $888.96 |
| Washington Quarters | 560 | $0.25 | 90% | 0.18084 | 101.27 | $3,888.77 |
| Walking Liberty Halves | 240 | $0.50 | 90% | 0.36169 | 86.81 | $3,333.50 |
| Peace Dollars | 80 | $1.00 | 90% | 0.77344 | 61.88 | $2,376.19 |
| TOTAL | 1,200 coins | $500.00 face | — | — | 273.11 ozt | $10,487.42 |
Robert and Linda bought 20 troy oz of .9999 gold bars in early 2019 at $1,350/ozt ($27,000 total). With gold at $3,280 in April 2026 they decided to sell. They assumed they’d pay their normal 15% long-term capital gains rate. Tab 3 showed them a very different number.
David monitors the gold-to-silver ratio and acts when it moves significantly above or below the 20-year mean. In April 2026 the ratio hit 85:1 — historically elevated — signaling silver as undervalued relative to gold. He used Tab 4 to model a 5 oz gold → silver swap before executing.
Patricia received a glossy mailer from a Gold IRA company promising “inflation-proof retirement wealth.” The proposal showed gold’s 10-year price appreciation and implied her $75K would grow substantially. She used Tab 5 to find out what the pitch wasn’t showing her.

❓ Gold & Silver Appraisals, Purity Testing & IRS Tax FAQ
The most common questions from gold buyers, silver stackers, coin collectors, IRA holders, and active traders — all answered with real numbers and direct references to the right calculator tab.
Melt value is the raw dollar value of the pure precious metal inside a piece, calculated using today’s spot price and the item’s purity. Market value is what a buyer actually pays — which includes collector premium, rarity, condition, and dealer markup on top of melt.
A troy ounce (ozt) is the standard unit for precious metals and weighs 31.1035 grams. A regular avoirdupois ounce (the one you use to weigh food) is only 28.3495 grams. If you confuse the two you will overstate your gold’s value by about 9.7%.
Always select “Troy oz” in Tab 1 when entering bar or coin weights. Use “gram” for jewelry weighed on a kitchen scale.
Hallmarks are the millesimal fineness — the number of parts per thousand that are pure metal. They map directly to karats and purity percentages used in the calculator.
| Hallmark | Karat / Grade | Purity % | Common use |
|---|---|---|---|
| 999 | .999 fine | 99.9% | Bullion bars, coins |
| 750 | 18K gold | 75.0% | Fine jewelry |
| 585 | 14K gold | 58.5% | US jewelry (most common) |
| 375 | 9K gold | 37.5% | UK/European budget jewelry |
| 925 | Sterling silver | 92.5% | Silverware, jewelry |
| 958 | Britannia silver | 95.8% | UK hallmarked silver |
Breakeven spot price is the future gold (or silver) spot price at which your all-in purchase cost equals zero profit — the minimum price the metal must reach before you are in the money.
Formula: Breakeven = Purchase price ÷ Fine metal weight (ozt)
These are regional weight units still actively used in specific jewelry and bullion markets. The calculator supports all four so you can price items priced in any global market.
| Unit | Grams | Region | Common for |
|---|---|---|---|
| DWT (Pennyweight) | 1.5552 g | US jewelry trade | Scrap gold buying |
| Tola | 11.664 g | India, Pakistan, Bangladesh | Gold jewelry, dowry |
| Baht | 15.244 g | Thailand | Thai gold chains/bars |
| Tael | 37.429 g | Hong Kong, China, Taiwan | Chinese gold bars |
A brand-new 90% silver quarter has a theoretical silver content of 0.18084 troy oz. But circulated pre-1965 coins have been handled for decades and lose a small amount of metal to wear. The industry-standard 0.715 factor accounts for this and reflects the actual recoverable silver per $1 of face value from a typical circulated bag.
Yes, but they are 40% silver — not 90%. Kennedy halves from 1965–1969 are a different, often-overlooked category. They contain 0.14792 troy oz of silver each versus 0.36169 ozt for a Walking Liberty half. Post-1970 Kennedy halves are clad (no silver) and worth face value only.
It depends heavily on the date, mint mark, and grade. Common-date Morgans in lower grades (VG–F) typically trade at or near melt value with a small premium. Key dates (1893-S, 1895, 1903-O) can trade at 10x to 100x+ melt. Tab 2 gives you the melt floor — always check PCGS or NGC population reports before selling any Morgan or Peace Dollar purely at spot.
The IRS classifies physical gold, silver, platinum, palladium, and collectible coins as “collectibles” under IRC Section 1(h)(4). Long-term capital gains on collectibles are taxed at a maximum rate of 28% — regardless of your income bracket — which is higher than the 0%/15%/20% long-term rates that apply to stocks and real estate.
| Asset type | Long-term rate | Short-term rate |
|---|---|---|
| Physical gold / silver / coins | 28% max | Ordinary income (up to 37%) |
| Gold ETF (e.g. SPDR GLD) | 28% (also a collectible) | Ordinary income |
| Gold mining stocks | 15% or 20% | Ordinary income |
| Futures contracts (1256) | 60/40 blend ≈ 23% | 60/40 blend ≈ 23% |
The 28% collectibles rate applies to all physical precious metals — gold, silver, platinum, and palladium — in any form: coins, bars, rounds, ETFs backed by physical metal, and jewelry sold as an investment. It is not limited to coins.
Yes. Capital losses on any precious metal can offset capital gains on any other collectible or capital asset in the same tax year. If your silver position is down and your gold position is up, selling both strategically can reduce your net taxable gain — a technique called tax-loss harvesting.
The ratio tells you how many ounces of silver it takes to buy one ounce of gold at current prices. A higher ratio means gold is expensive relative to silver (or silver is cheap). A lower ratio means silver is expensive relative to gold. Historically the ratio has averaged around 55–65:1 over the 20th century.
In Tab 4, you enter your holdings for each metal (gold, silver, platinum, palladium, copper) by weight and purity. The calculator fetches live spot prices, multiplies by fine metal weight, sums them up, and shows each metal as a percentage of your total portfolio value in a donut chart.
A typical Gold IRA involves four separate fee layers that most promotional materials downplay: an initial dealer markup (5–15%), an annual custodian fee ($75–$300), an annual storage fee ($100–$300 depending on segregated vs commingled), and a liquidation spread when you eventually sell (2–5%).
The IRS requires gold held in an IRA to be at least 99.5% pure (.9950 fineness or better) under IRC Section 408(m). This means American Gold Eagles, Canadian Maple Leafs, Australian Kangaroos, and .9999 bullion bars all qualify. Standard 22K (.916) coins like the South African Krugerrand do not qualify.
| Metal | IRS minimum purity | Qualifying examples |
|---|---|---|
| Gold | .9950 (99.5%) | American Eagle, Maple Leaf, .9999 bars |
| Silver | .9990 (99.9%) | American Silver Eagle, Maple Leaf |
| Platinum | .9995 (99.95%) | American Platinum Eagle |
| Palladium | .9995 (99.95%) | American Palladium Eagle |
DCA means investing a fixed dollar amount at regular intervals (e.g., $200 every month) regardless of price. When gold is cheap you automatically buy more ounces; when gold is expensive you buy fewer. Over time this lowers your average cost per ounce versus trying to time lump-sum purchases.
Under the SECURE 2.0 Act, the Required Minimum Distribution (RMD) age is 73 for anyone born between 1951–1959, and 75 for anyone born in 1960 or later. A Gold IRA is subject to the same RMD rules as a traditional IRA — the custodian must liquidate or distribute metal to satisfy the RMD each year.
Spot prices are fetched from a market data feed on page load and typically reflect a short delay from the live market. The timestamp is shown next to each spot price in the calculator. For financial transactions, always confirm prices with your dealer or broker at time of execution.
No. All calculations happen 100% in your browser (client-side JavaScript). No weights, prices, portfolio values, or personal information you enter are transmitted to, collected by, or stored on USFinanceCalculators.com servers. You can even use the calculator offline once the page loads.
Click the 📄 PDF Report button inside any tab to generate a business-grade valuation report that includes the spot prices used, your inputs, all calculated outputs, and a timestamp. The WhatsApp share button generates a formatted text summary you can send instantly from any device.
Use Tab 1. Select your metal (Gold), choose the hallmark (usually 14K = 585 or 18K = 750 on US/European jewelry), enter the weight in grams, set the dealer buy premium to 0% to see melt value, then enter the typical scrap dealer discount (usually −20% to −40% below melt) to see what a pawn shop or refiner actually offers.
Yes. Tab 1 supports all five metals: Gold, Silver, Platinum, Palladium, and Copper — each with their own live spot price feed. Tab 4 tracks all five metals in the portfolio tracker simultaneously. The 28% collectibles tax rate in Tab 3 also applies to platinum and palladium held physically.
Open the calculator and run your specific numbers — most answers become clear once you see your own melt value and breakeven in real time.
