Help With Possible Error: Canadian 1999 Quarter

Someone dropped acid on it

Curious how perfectly round it is.



to the CCF!

Thanks for the info.

I was also curious about how its almost a perfect circle.
but this is why I posted it here as I'm no expert just looking for info.

Also curious, if you look closely there's a rim or raise ridge around that circle.

Anyways maybe more can chime in but for now I'll have to pass it as someone put Acid on it.

Once again thanks for the help, guys.

P.S. since I have lots of free time on my hand at the moment, I have other coins I'll be posting that I have questions about

Thanks for The Info.

I do believe the theory of something being glued on and then removed is definately more plausible than the acid theory.

just one thing is still a mystery to me is why there is a rim/ridge around the center part. although you cannot see it in the photo is that the center piece is slighter higher than rest of the coin. I tried to photograph that but I was unable to take a good photo. but the center piece is definately higher and like I said has a rim/ridge.

I uploaded one pic but still hard to show how the center piece is higher. In person you can see it and feel it. Once everything gets back to normal I'll go to the local coin shop to get it looked at before I spend it in the gum machine. lol
