Here's the link to Coppercoins. See if you have the reference markers. Pics are too magnified to confirm alignment, but the mark at 2:30 on the MM is in the same location...just can't tell if it's a well placed ding. Have a look: http://www.coppercoins.com/lincoln/diestate.php?date=1956&die_id=1956d1mm002&die_state=mds
Bradford, understand something. Those wheat cents, as well as the earlier memorial cents, were made by dies that were actually pressed twice by the hubs to reinforce their designs. That's why sometimes a die is "doubled." And, of course, if the die is doubled, and the die makes the coin, that doubling is naturally going to show up as doubling on the coin. It can't miss. And that's what you're looking for in these early cents. You're looking for two separate images, side-by-side, both of the same height off the coin, one of which will be full, and the other of which will be partial. Anything less is due to the strike itself, or a deteriorated die. Keep that criteria in mind the next time you think you're seeing a doubled die on those early cents. If what you're seeing doesn't satisfy that criteria, there's a 99.99% chance it's not from a doubled die. And the percentage may even be higher than that. Hope this helps you some.
