Got this penny as change and it has some interesting marking. The inner rings Front and Back in places are Double. They Actually run through the Top of the letters on the back. Touching L on Front. Also the C and A appear to Touch on America.
Clicking on pics shows better detail of errors. Last night I noticed the S on States ( back) looks Smaller because its cut off by inner line. Dont know if its worth anything, but hust as well save it.
