This was not done by any machine in the dryer it would not be that conformed and round don't make sense to me. This was done by human hands jazzcoins Joe
There is no reason that a coin in a dryer would suffer deformation of the rim only. The damage is overall. This is a dryer coin This is a "spooned" coin
The cent has potentially been in the dryer longer, and coppernickel is harder and more resistant to marks than the copper cent. It will alo depend on what else is in the dryer fin with the coin. If the coin is basicly by itself you won't get the fields all marked up. If you have sand, other coins, other small hard objects like nuts, screws, small rocks etc the fields will get badly marked up. So a marked up piece is definitely from a dryer, but you can't say an unmarked up one isn't.
I can say it. Look at dimes from your pocket change and you'll see they're marked up and nicked. Now, if a dime undergoes enough accidental trauma to fold the rim over, it WILL show more than a little damage and/or marks and scrapes on the portrait and fields, whether it's hard nickel, soft gold or anything in between.
