Use the following calculator to determine the silver value in various amounts and combinations of 90% junk silver coins and war nickels. Often sellers on eBay will have lots with different combinations of junk silver. I made this calculator so I can easily determine the value of the lots. You can also use this calculator to determine the total value of all your junk silver.

Calculator Instructions
To calculate the value of silver in a coin, multiply the silver weight in troy ounces (not the coin weight) by the silver spot price. For example, A junk silver quarter has a silver content of 0.1808 troy oz. If the silver spot price is $10/troy oz then the quarter's value is $10 * 0.1808 = $1.81. This calculator will factor in 1% loss of silver due to wear from circulation (which is common in junk silver coins). The seller will often add a markup.
