This is the most unusual coin I have seen. Please look at the photos b4 everyone says PMD. Notice how the date is punched over the raised metal blobs. What in the world is this called? Mike Diamond I hope you are out here today! Thx
+1 Gas bubbles. If this were to have come from the press like this, there'd be thousands out there just like it.
It's some form of post-strike damage. The reverse face is in horrid condition, and I expect this is from the same forces that generated the strange topography on the obverse face. I'm quite sure this is nothing a coinage press could produce.
I agree, looks like a welding tip touched the reverse and caused the obverse damage. Cents have been used in the past, (I was taught using this method), of testing a welding tip to see if its hot enough to use. Unfortunately a lot of people do not treat coins with the respect we do.
The zinc has become rotten underneath the super thin copper coating and has swelled the copper layer up into this shape.in other words this cent is almost totally gone , if someone was to bend it this coin would fall apart. when the zinc rots it swells up then it becomes loose and grainy like sand. when our zinc coins are found with a metal detector they usually are in such bad condition they won't go thru a coin counter.
To realize what the guys are saying, take a hard plastic like the end of a ballpoint pen tube and try to press some of the blobs down to see if they are hallow underneath. Since I believe they are, you will see that the plating was lifted by gas forming underneath it. Reaction to the Zinc as caused by rot or by extreme heat will force the plating upward. Toss that sucker back to Coinstar.
I'm with diggit on this. It does look like it was in a fire........probably a "hand-held fire" like a torch. Note how the reverse has a blackened indentation in approximately the same position as the largest blob of melted metal on the obverse. This appears to be where the heat was the most intense and caused the metal to melt through to the obverse. Chris
