Maybe the rim was sanded down it looks a little out of round.

edit: Here's a link to the "Coin Shrinker" very good video.

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?

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.

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.

Electrical shock would cause discoloration, tarnish.
This looks more mechanical.

Sorry Matt didn't see that.

So 3.24 g is regulation.

Strange piece.

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.

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.

"It causes the quarter to be squished magnetically" - now that's a sophisticated scientific explanation! So, what kind of evil sorcery is at work here?

Alluded to in link to a previous thread but you'd have to dig for this link - http://teslamania.delete.org/frames...gallery.html I'd guess it was done with a not quite so dramatic amount of joules.

The reduction in size, the slightly concave edge, and the subtly warped surfaces indicate that this was an encased, or "lucky token" cent. It was once surrounded by an aluminum ring bearing an advertisement or other message.

> "It causes the quarter to be squished magnetically"

But, by conservation of mass, they get much thicker.

I've seen examples of acid bath where things seem to shrink proportionally.
