Calculate the intrinsic value of your silver coinage based on current spot prices.
US 90% Silver (Dimes, Quarters, Halves pre-1965)
US Morgan/Peace Dollars (90% Silver)
US 40% Silver (Kennedy Halves 1965-1970)
War Nickels (35% Silver – Per $1.00 Face Value)
Canadian 80% Silver (Pre-1967 – Per $1.00 Face)
Total Silver Content: 0.00 troy ounces
Estimated Melt Value: $0.00
Understanding Coin Silver Value
This calculator determines the intrinsic metal value of "junk silver" or coin silver. Most US silver coins minted in 1964 and earlier contain 90% silver. Because of wear and tear, the industry standard for $1.00 in face value (any combination of dimes, quarters, or halves) is approximately 0.715 troy ounces of pure silver.
Common Conversion Factors:
90% Silver Dimes, Quarters, Halves: $1.00 face value = 0.715 troy oz.
90% Silver Dollars (Morgan/Peace): 1 coin = 0.7734 troy oz.
40% Silver Halves (1965-1970): $1.00 face value = 0.295 troy oz.
35% War Nickels (1942-1945): 1 nickel = 0.05626 troy oz ($1.00 face = 1.125 oz).
Example Calculation:
If you have $10.00 in face value of 90% silver quarters and the silver spot price is $24.00 per ounce:
Silver Content: 10.00 x 0.715 = 7.15 troy ounces.
Melt Value: 7.15 x $24.00 = $171.60.
Note: This calculator provides the raw melt value. When selling to a dealer, expect to receive slightly less than the melt value (a spread), and when buying, expect to pay a premium above melt.
