A member of the numismatic society put into circulation a 1909S wheatie, and two other valuable wheat pennies, out in the general public so check your change, Also they have found some 2004 wisconson quarters that are mint errors, It said they can't figure out how it happed , but there is an extra leaf on the ear of corn and some markings in that area. I guess they are going for 600 big ones at auction, so check every time your handed that bit o' cad from the store , who knows who will find it. Probably someone who doesn't even realize what they have. smg
