Silver melt value is the intrinsic metal value of a silver item based on its weight, purity, and current spot price. The formula converts grams to troy ounces, applies the purity percentage, then multiplies by the spot price. Every silver item, from a junk silver dime to a 100 oz bar, follows the same three-step calculation.
If you hold silver to meet religious giving obligations, note that silver nisab (the minimum threshold for zakat) is 595 grams (approximately 19.1 troy oz) of silver. The Zakat Calculator applies this silver nisab automatically to determine your annual zakat liability on precious metals holdings.
"Junk silver" is the dealer term for US dimes, quarters, half dollars, and dollar coins minted before 1965. These coins are 90% silver and have no numismatic premium and trade purely on silver content. The standard shortcut: every $1 of face value in 90% junk silver contains approximately 0.715 troy ounces of silver.
| Coin | Weight | Purity | Silver (oz) |
|---|---|---|---|
| Mercury / Roosevelt Dime | 2.50g | 90% | 0.0723 |
| Washington Quarter | 6.25g | 90% | 0.1809 |
| Walking Liberty / Franklin Half | 12.50g | 90% | 0.3618 |
| Morgan / Peace Dollar | 26.73g | 90% | 0.7735 |
At $28.50/oz spot, $1 face value of junk silver = 0.715 × $28.50 = $20.37. A $1,000 face value bag contains ~715 troy oz worth approximately $20,370. Select any coin from the preset dropdown above to calculate melt value instantly.
Sterling silver is 92.5% pure silver, marked .925 on jewelry, flatware, and holloware. It is the standard for most silver jewelry sold in the US and UK. To use this as a sterling silver calculator: select "Custom" in the preset dropdown, weigh the item in grams on a digital scale, enter the weight, and set purity to 0.925.
Jewelry dealers typically pay 70-85% of melt for sterling pieces due to refining costs. Flatware and larger sterling items with less labor content often fetch 85-92% of melt. If you are building silver into a long-term investment portfolio, the Coast FIRE Calculator can show whether your precious metals holdings contribute to your financial independence timeline at an assumed growth rate.
You have 20 Morgan Silver Dollars. Silver spot price is $28.50/troy oz. Each Morgan weighs 26.73 grams at 90% purity.
To model the return on a silver investment over multiple years, accounting for purchases at different prices and eventual sales, the IRR Calculator handles uneven cash flows that a simple silver price formula cannot capture.
