pimpim Valued Member Canada 111 Posts	Posted 08/11/2017 5:06 pm I've found a Newfoundland cent with a very thin flan. My picture contains a normal cent 1917. The normal cent has a weight of 5,5 gr and a diameter of 25,5 mm and the odd cent weighs 2,3 gr with a diameter of 24,5mm. I wander if this cent is an error of the mint or it is a novelty. The strike is quite blurr and I don't understand how the mint could fabricate that kind of error because of it's thinnest and the cent is perfectly round. Here are the pictures I've taken with my cell phone. I hope that it will be clear to understand my description. Report this Post to the Staff

sel_69l Bedrock of the Community Australia 21788 Posts	Posted 08/11/2017 5:24 pm This coin is quite genuine. It has suffered from lamination, and a surface layer from both sided has spalled off. The surface layers have fallen off, after the coin was struck, thus showing an indistinct image on what is left of the coin. The fault has it's origins in the rolling of the bronze strip before the blank was punched out. A common reason for the lamination is a drop of oil has dropped on the strip during the rolling process and has spread out. Report this Post to the Staff
Altaira Pillar of the Community Canada 2519 Posts	Posted 08/11/2017 5:30 pm It's not an error, the coin was soaked in acid. Acid eats away from all surfaces leaving a thinner, smaller coin, with devices and lettering also thinned out. Report this Post to the Staff

biokemist6 Bedrock of the Community United States 12437 Posts	Posted 08/11/2017 5:55 pm Indistinct devices plus lack of a rim(reduced diameter) equals chemical erosion. Report this Post to the Staff
sel_69l Bedrock of the Community Australia 21788 Posts	Posted 08/11/2017 6:14 pm Although I have seen quite a few full lamination errors, the acid explanation could well be right. I note that there is a minor, but distinct difference in the diameter of the two coins pictured. Lamination would produce a result where the core would remain at the original diameter, and that does not appear to be the case here. Report this Post to the Staff

Alan Pillar of the Community Canada 1463 Posts	Posted 08/11/2017 10:07 pm Is acid yes I agree all devices shrunken equally. Dies can't do that. Report this Post to the Staff
okiecoiner Pillar of the Community Canada 5593 Posts	Posted 08/12/2017 04:38 am It doesn't really have to be "acid" as we know it ... coke or Pepsi will do the same thing (or at least used to). You have to change the liquid out after a while. Report this Post to the Staff
pimpim Valued Member Canada 111 Posts	Posted 08/28/2017 09:33 am Thank you for your commentaries. I will test myself the acid job and I will give the results eventually. Report this Post to the Staff
