1969-D Lincoln Cent, Really Light Press?crunched Left Edge? Keeper?

My guess would be that it was struck with worn dies and was heavily circulated. The Die Deterioration is obvious from the looks of the swollen devices, but it also shows signs of being in circulation for a long time.

As a die deteriorates, the metal flows outward towards the rim. If it gets bad enough devices will get lost in the rim. So, yes. Die Deterioration does explain the "crush."

Looks like a Dryer Coin to me also.

Looks abused. It wan't struck that way. Looks like it may have been squashed and it flattened the devices. PSD. But if anyone has a rock tumbler and would like a project, I would like to see a copper cent, a zinc cent and other denominations put through a rock tumbler to see for sure what happens to them. Take images like per step of the process to show what happens to them. (I've always thought these coins may have been put through that process. But it would make a great project if someone has a rock tumbler. Put some rocks in there also) I feel this is not a Dryer Coin as the rims are not rolled over like you would find on a Dryer Coin.

That was my thought on this coin as well. I never considered a rock tumbler. I did consider heat as the culprit, but clearly it was something other than, or in addition to, worn dies.

It only tumbled a few cycles, but on high heat!
