a must see error

[michealvince]

i have had his coin for a while and can not figure out what kind of error this is. Someone said grease on the die. There is nothing on this coin like glue or epoxy and Ext. Definitely a error

I would say post-mint damage. Looks like someone tried to electroplate it.

Please refer to the posts made when you posted the same coin earlier this year.

Time for more coffee.

Some kind of foreign substance on the coin, not an error.

it's a must see and I must say that it looks like the result of a couple of coins being stacked/stuck together in the bottom of the cup holder in someone's car after they've been swimming in a good amount of moisture from the sweaty drink cup

Soda stain.

Not to worry. It's probably still worth 1¢ though; especially if you try to spend it with other coins or hidden in a 50¢ roll.
