I deal in coins as well as gems and jewelry, we often will go to 10%
below melt on legal tender silver coins. These circulate in bags of
$100, $500, and $1000 face value at bullion prices and sell readily.
A great way to sell them is to locate a local coin show and take them
to dealers there. Right now you may be able to get up to 24-25 X face
value for US silver coins. I'm currently buying at 24 X face for
coins without major problems and with readable dates.
