Basis
Pre-1965 90% dimes, quarters and half dollars: $1 face = 25.00 g of coin at .900 fine = 22.50 g fine silver
Worked out from NIST Special Publication 811, Guide for the Use of the International System of Units - the 1959 international yard and pound agreement fixes 1 grain = 64.79891 mg exactly, so 1 troy ounce = 480 grains = 31.1034768 g and 3 other sources.
The spot price you entered is the only price used. It carries no dealer spread, refining charge or assay, and the result is not a quote.
A metal-content valuation only. It uses the spot price you enter, applies no bid/ask spread, refining loss, assay, numismatic premium or tax, and is not an offer or an appraisal.

How this is worked out

4 steps
  1. $1 face = 25.00 g of coin at .900 fine = 22.50 g fine silver.
  2. $1 face value x 22.5 g fine per $1 = 22.5 g of fine silver.
  3. Fine metal = 22.5 g / 31.1034768 g per troy ounce = 0.72339 ozt.
  4. Melt value = 0.72339 ozt x 2400 = 1736.14.
