I have the entire 2009 collection of the US Territory quarters, and just the other day, I found a 1841 penny.
I live on a dirt road, and the driveway to my house is slightly uphill. After a rainstorm, I walk the drive to see what I can find. Usually it's pieces of broken pottery, a few arrowheads, some old-fashioned nails that were made by a blacksmith.
But the other day, I found what looked like an old pop bottle cap, but when I cleaned it up, it was a 1841 1-cent piece, about the size of a quarter.
A collector magazine says it's worth about $25....
