I’m sitting on a gold mine…

Since 1982 pennies have been made of 97% zinc. But before 1982 they were
95% copper.

By my calculations 154 pennies contain about a pound of copper. Recently
copper was at about $1.54 per pound. It - along with silver and gold and
most other metals - has been trending up for the last two years or so, and
is likely to continue to do so.

Save your (pre-1982) pennies. They're worth more than a penny. Last time
this happened was 1964 when dimes and quarters contained more than $.10
and $.25 worth of silver.
