John1 Moderator United States 56855 Posts	Posted 03/14/2023 09:03 am I agree with a bubble. It is a copper plating issue. John1 Report this Post to the Staff

Michael1977 New Member United States 5 Posts	Posted 03/14/2023 5:27 pm So this wouldn't be considered an error coin. I appreciate everybody helping me out on the coin as well. Report this Post to the Staff

Petespockets55 Pillar of the Community United States 5787 Posts	Posted 03/14/2023 9:24 pm There also appears to be a hole in the left planter on the stairs cause by the same effect. A hole in the copper plating allows air to enter and oxidize the zinc. Words of encouragement are one of the major food groups. We need to consume them regularly to thrive and grow.

Michael1977 New Member United States 5 Posts	Posted 03/16/2023 2:33 pm It's raised up . If you were to push the plating back down, if you could. seems lthere would be too much material to go back in place. I'm going to take the advice from seven people that's it a blister/ bubble It just looks like it was stamped in almost. I'll keep looking through my Pennies.

Michael1977 New Member United States 5 Posts	Posted 03/23/2023 10:34 pm If it's popped up wouldn't it have come off the coin Report this Post to the Staff
Cujohn Pillar of the Community United States 7174 Posts	Posted 03/24/2023 4:16 pm No. The plating would expand to a certain point, after that it would rupture. It's just a cent so that's all it will ever be worth, so take a toothpick and see if you can rub the plating off at that site. Report this Post to the Staff
