Hello, I have a 1979 canadian dime, I know there is really nothing special about that year, but I have found something strange with it, the outer part of the dime is way thicker than it should be and around the r where it's supposed to be "ribbed" or whatever you call it, it isn't, very smooth, I can't seem to upload a pic, but I'm sure one of you guru's knows what I'm talking about.... I'm kinda new at this, is this a kind of rare thing to happen??
I will try to upload a pic of it again..
