Not much to say here,
I have been interested in coins for quite a few years and with the rising copper prices (falling US
dollar value) it became aware to me that the older copper pennie in circulation would be worth
more in intrinsic value than face.  I had no idea that it would happen so fast.  3 years ago I
sorted my piggy bank pennies by hand for the pre 1982 coins of copper composition.  after
sorting off about $9 dollars face of copper coins from my stash, I put the idea down and
pondered how to do it automaticaly.
In January of 2006 I built the first prototype and the rest as they say, is history.
