I would like to see the area where the sealer touched the cent. It should be interesting.

I'll try to get a better image, but the sealer didn't just touch the cent, it put several parallel slices into it which indicates that the sealer uses quite a bit of pressure and I would imagine a bit of heat as well. This anomaly (or whatever you want to call it) also tells me that the sealer is rotary.

The planchet is zinc, so it is pretty soft. Try sliding the coin into an open area if possible. If not no biggie. But I'm thinking it would be more checkerboard than just straight lines?

It's not a problem sliding the penny into a more visible location. That's how I noticed the damage. I thought it was just a broken seal. I saw the penny starting to tarnish and bought a replacement set. When I took this one out of the album I saw the tracks on the face of the penny. Then I looked more closely at the seal on the edges and deduced that a rotary sealing device hit the penny and raised up for about 2 cm and didn't texture the edges adjacent to the location of the penny.

The slashes are in one direction on the obverse and perpendicular on the reverse. That cross-hatching is done in one direction from the top and the other direction from the bottom. I would be willing to bet I'm not the only one that learned something interesting about how these sets are manufactured!   |

Pretty interesting. I've never seen nor heard of one before. Thanks for sharing.

It's interesting to see another coin with the same damage. This must not be that rare of an occurrence in the mint packaging process. It looks like it did more damage to your penny because the metal composition is copper-zinc as opposed to the cupro-nickel composition of the quarter. That's just my theory anyway.

That would make sense. I was just surprised by how much pressure the sealers apparently use and that they have blades parallel to the direction of travel on top and blades that are perpendicular on bottom. You didn't show the reverse of your quarter. Where there marks on the reverse perpendiculat to the ones on the obverse? |

Strangely enough the reverse didn't have any of those marks which is why I didn't show it. I can see it now, the next big thing: COINS DAMAGED BY PACKAGING SEALERS!  |

Just found ANOTHER one - this time a nickel in a '93 Philly set. Keep in mind, I am NOT a dealer. When I get a mint set I don't buy any more, so looking through just ONE example each of '68 to '06 P & D (including '82 and '83 P & D Souvenir Sets), I found TWO with a damaged coin. I looked over EVERY set with a magnifying glass LOOKING for damaged coins, but it does make me wonder how many folks have uncirculated sets put away with damaged coins in them. Could be an unpleasant surprise! Sure was glad there was no damage in the '82 and '83 sets!

I did a search and found these on this site: Bicentennial quarter - Philly Mint (mentioned earlier) https://goccf.com/t/1169971975 penny - Denver Mint https://goccf.com/t/1146521997 dime - Denver Mint https://goccf.com/t/109104Add the two that I found and that's FIVE examples of coins damaged by the uncirculated set package sealers. Two from Denver and three from Philly. There may be others on this site that my search didn't find. If part of your collecting philosophy (like mine) includes Uncirculated Mint Sets, you may want to give them all a close inspection for damage from the sealers! |
