matttheriley Pillar of the Community United States 1512 Posts	Posted 02/02/2015 3:44 pm Hi Everyone, I need your help on this one. I was going through my Canadian small cents the other day and was stacking my 1949's when I noticed this one "felt" weird in the stack. It is approximately 1mm smaller in diameter! Is this an error and how would this occur? I also notice there is a flaw on the reverse or a die clash or something. What do you think? Thanks! Report this Post to the Staff

ace_ftw Pillar of the Community Canada 1747 Posts	Posted 02/02/2015 3:58 pm What is the weight? it does look like a die crack running NE to SW, not sure about the diameter, I have never seen a coin like that. I have seen experiments where (I think its under extreme pressure) the coin is shrunk, with no damage. The "Die Crack" may be the result of squishing, as mentioned the width looks slightly off as well. Report this Post to the Staff
thedollarman Pillar of the Community Canada 4911 Posts	Posted 02/02/2015 4:09 pm I think the coin was electrically shrunk which caused pre-existing planchet problems to turn in to a lamination flaws on the reverse.

SPP-Ottawa Moderator Canada 10458 Posts	Posted 02/02/2015 6:07 pm I checked my files, the Royal Canadian Mint did not make coins for any foreign countries at all during the 1940s. The closest thing to that size that the RCM made, would be the 1937 Dominican Republic 1 Centavo (bronze), it is unlikely that it was hanging around the mint - 12 years later. The coin does not look quite "round" to me, what does the rim look like? What is the weight?

matttheriley Pillar of the Community United States 1512 Posts	Posted 02/02/2015 6:20 pm It weighs 3.3 grams. Here is a picture of the rim compared to another 1949. They appear to be the same thickness. Sorry this picture is not the best. Report this Post to the Staff
rocky Pillar of the Community Canada 2784 Posts	Posted 02/02/2015 6:21 pm well before breakers in electrical panels. some people use to install a penny a head of the glass fuse. a very dangerous practice. those marks on your penny maybe arch flashes. as the load increased. the hotter the penny would get and so it would arch over. causing burns not sure if this is what happen to your penny but might be. if it is the penny would be very harden. as the heat expanses the copper and when it cool it shrinks.

SilverDon Pillar of the Community Canada 2360 Posts	Posted 02/02/2015 6:34 pm Electrical shock would cause discoloration, tarnish. This looks more mechanical. Sorry Matt didn't see that. So 3.24 g is regulation. Strange piece. Edited by SilverDon 02/02/2015 6:38 pm Report this Post to the Staff

matttheriley Pillar of the Community United States 1512 Posts	Posted 02/02/2015 7:08 pm No worries Don. I saw you 'edited' your post right when I re-posted the weight. My scale only measures to the nearest tenth of a gram, so it may be 3.29 or 3.31. I am quite perplexed. Is there any other images you guys want, I'll shoot them tonight if I get time. One I think I want to do is I'll trace around another 1949 cent and then take a picture of this coin inside the outline. That could be used to see how out of round it is.

SPP-Ottawa Moderator Canada 10458 Posts	Posted 02/02/2015 7:35 pm 3.3 grams is within mint tolerances for normal coins. If you don't believe me, weigh about two dozen George VI 1-cent coins, you'll be surprised at the variance.
