Matteproof Pillar of the Community Korea, Republic Of 1881 Posts	Posted 03/06/2018 11:00 am I found something interesting going on around the edge of this 1981 S. Korea 5th Republic commemorative 100 won. From a certain point on the middle of the edge, a "crack" continues well into the rim of the coin. This seems to have happened most certainly during the minting process as I've never seen PMD appear like this coin, if it happens to be PMD after all. All opinions would be appreciated. Thanks! Here are the pics: Report this Post to the Staff

Crazyb0 Rest in Peace 10197 Posts	Posted 03/06/2018 12:06 pm Nfine, it was caused by a sharp edged object, knife blade-like. It is highly unlikel for it to be machining or die error, only thing it could be is a struck through of a fibrous material to have transversed the angles involved along the die and strike chamber. If you were to look straight on, not angled like your pix, you would see a very slight rise of metal on either or both sides of the cut, the metal is moved that way in PMD. In a strikethru, metal is compressed evenly around the recessed( pushed into) object, so no metal height is encountered. Hope that makes cents!

Thank you for taking the time to explain what most likely happened to this coin. As I mentioned, I'm just now learning how to determine PMD from something that may have happened in the manufacturing process. Report this Post to the Staff
