Silver Coin Melt Value: How to Calculate What Your Coins Contain
Silver coin melt value is the market value of the fine silver inside a coin. Calculate it by multiplying gross weight by silver fineness, converting to troy ounces, and multiplying by a timestamped silver spot price. Melt value is a baseline, not automatically the retail price, collectible value, or dealer offer.
The Silver Coin Melt-Value Formula
Melt value = gross grams × silver fineness ÷ 31.1034768 × silver spot. Enter 90% as .900, 40% as .400, and .999 as .999. Precious metals use troy ounces, not household ounces.

Common U.S. Silver Coin Content
| Coin | Purity | Approximate fine silver |
|---|---|---|
| Pre-1965 dime | 90% | 0.07234 troy oz |
| Pre-1965 quarter | 90% | 0.18084 troy oz |
| Pre-1965 half dollar | 90% | 0.36169 troy oz |
| Morgan or Peace dollar | 90% | About 0.77344 troy oz |
| Modern Silver Eagle | .999 fine | 1.0000 troy oz |
Worked Example
An unworn 90% silver quarter weighing 6.25 grams contains 5.625 grams of silver, or about 0.18084 troy ounce. At a hypothetical $50 silver spot, its melt reference is about $9.04. This is an example, not a current quote; wear can reduce mass.
Melt Value vs. Retail and Dealer Offers
Retail price includes the manufactured product and its premium. A dealer bid depends on the exact coin, authentication, wear, quantity, demand, market timestamp, and transaction costs. Check dates, mintmarks, condition, and varieties before treating an older coin as bulk silver.
How to Compare a Dealer Offer
A melt calculation gives you a reference point, but a dealer offer is a separate transaction quote. Before accepting an offer, compare the same coin type, quantity, condition, and timestamp, then ask whether the quoted amount is a dealer buyback price or a retail selling price.
- Identify the exact composition and fine-silver weight.
- Record the spot-price source and time used for your comparison.
- Separate bulk or circulated silver from collectible dates, mintmarks, varieties, and graded coins.
- Ask whether testing, shipping, payment, or other transaction costs affect the net amount.
- Compare the written offer with at least one other current quote when practical.
How to Calculate a Mixed Lot
- Separate coins by type and composition.
- Record weight and purity for each group.
- Calculate fine-silver troy ounces.
- Apply the same spot source and timestamp.
- Check collector value before accepting a melt-based offer.

Frequently Asked Questions
How do I calculate silver coin melt value?
Multiply gross grams by fineness, divide by 31.1034768, and multiply by silver spot per troy ounce.
How much silver is in $1 face value of 90% coins?
Original-mint math is about 0.7234 troy ounce; circulated material is often estimated around 0.715 troy ounce because of wear.
Is a Silver Eagle worth only melt value?
No. Recognition, condition, year, packaging, and product demand can support a premium above melt.
What is the difference between silver spot price and melt value?
Silver spot price is the market benchmark for a troy ounce of silver. Melt value applies that benchmark to the fine-silver content of a specific coin or lot, so the two figures are related but not interchangeable.
Why can a dealer offer be lower than a coin’s retail price?
A retail price includes the cost and premium of selling a finished product. A dealer offer is a buyback quote that may reflect current demand, testing, quantity, condition, transaction costs, and the dealer’s resale market.
Should every silver coin be valued only by melt?
No. Common circulated coins may be evaluated primarily by silver content, but dates, mintmarks, varieties, condition, certification, and collector demand can make some coins worth more than their melt reference.
