Understanding "Times Face Value"

The "Times Face" multiplier tells you how much to pay for a coin based on its metal content, ignoring its collector value. A 90% silver dime has the same silver content per dollar as a 90% silver quarter.

Calculation Factors:

90% Coins (Pre-1965): Uses a multiplier of 0.715 to account for wear in circulation.
40% Coins (1965-1970): Uses a multiplier of 0.295 for Kennedy Halves.
