Mac119 New Member United States 6 Posts	Posted 10/30/2019 11:04 am I am new to coin collecting and discovered a 1984 D Lincoln Penny that actually is stamped 11984. I can not find any information on this coin and it's the only one I've seen of it's kind. Any information would be helpful. I have been unsuccessful in posting pics to this site from my iPhone.

Chase007 Pillar of the Community United States 7516 Posts	Posted 10/30/2019 2:37 pm TO Community It is a well placed Linear gas bubble and not stamped by Mint. Another words: it is a trapped gas beneath the copper plating, not an error. check out the links below: http://goccf.com/t/181918 http://goccf.com/t/288070 http://goccf.com/t/275587 Edited by Chase007 10/30/2019 5:28 pm Report this Post to the Staff
Mac119 New Member United States 6 Posts	Posted 10/30/2019 2:48 pm I can see what you are talking about except that this bubble changes size and width at the exact Moment its next to the other number one. Report this Post to the Staff
Mac119 New Member United States 6 Posts	Posted 10/30/2019 2:50 pm Under a 10 times magnifier the one is the exact match to the other number one and its to the left of the bubble line. Report this Post to the Staff
Yokozuna Pillar of the Community United States 4618 Posts	Posted 10/30/2019 3:34 pm to CCF! It's a bubble of trapped gas between the copper plate and the zinc core. If you press on it with a wooden toothpick it should yield to the pressure. It's a common problem with "Zlincoln" cents. Once the plating is broken, the zinc will start to corrode under the right conditions. Once zinc rot sets in, the coin is a goner.

Jim0815 Pillar of the Community United States 5239 Posts	Posted 10/30/2019 4:35 pm Take a toothpick and run it over the bubble. If it flattens out its trapped gas, if it is solid and cannot be flattened then it's an incredible anomaly. Report this Post to the Staff
Mac119 New Member United States 6 Posts	Posted 10/30/2019 4:37 pm Tried to pierce the extra one on two spots with a needle. No change. Does it take a while for it to go down? It's the same hardness as the normal #1. Report this Post to the Staff
moxking Rest in Peace United States 17900 Posts	Posted 10/30/2019 4:41 pm Needles and coins are not friends. If you have any small blunt piece of wood - match stick or toothpick - to see if it's pushes down. Report this Post to the Staff
