Do not ignore copper either! Every U.S. Penny 1982 & ealier has 3 cents worth of copper! Buy rolls of pennies ...I found that about 1/3 of most rolls still are pre 1982 pennies....200% increase in value! Copper is now at almost $4 per lb!

Banks get rolls of coins from customers (don't bother with "Fed Wrapped" (all new stuff)....ask for the customer rolled quarters & dimes....1964 & earlier is 90% sliver...making a quarter worth about $6.
