One im sure is mis struck .the other im not sure.first 3 pics are from a 1988.you can see the 88.the laat 2 I dont know the year.
The off center looks copper to me. No evidence of plating being broken as would appear on '82 or later. The first one is definitely PMD.
$10 will get you 3 2L of Coke, tostitos chips, and 2 cans of fritos cheese. You can have your own little party with $10
The 1988 is definitely PMD. On the reverse, you can see the date from another coin backwards.....2006(?) Chris
On that '88 coin--has another coin been forced/smashed into the surface of the other coin? Pretty interesting damage.
That's what it appears. People will often squeeze or smash cents together to get interesting effects and in some cases, try to pass them off as genuine errors.
