I have a 1919 P wheatie too. Mine is so worn though...... I paid a quarter (Over Paid) But I love it. Most of yours are in good cond. A couple are worn -around the numbers- Like the 195? at the very bottom. Cool collection though.
The one in the pic is actually a 1919 S. I have a Philadelphia and S mint 1919. The P (not scanned) is it rough shape. Surprisingly all of these coins still have their shine - it just doesn't show on the scanner, even at 600 DPI, lol. That's a 1951 S at the bottom - it's in great condition - that's actually a mini bubble of copper right on the date!
