New dog or new camera?:smile It's hard to say with this pic. If you get a new camera and you take more pics, include the top of the ear too. There's a lock of hair that's doubled there and it would help to ID.
I keep hoping you will find another good one to show on here , hang in there and find some good ones. this one is just a normal cent that has taken a hit to the bottom of the ear. google 1997 doubled ear and you can see some good photos of a real one. a real one in mint condition sold on ebay last night for under 50.00 I didn't bid high enough on it and someone got a good deal. I went back and found the ended listing for the 1997 doubled ear cent coin so i'm including a link to it so folks can see what they look like. http://www.ebay.com/itm/1997-Lincol...vwnTU6NWATnXYbqqOciRo1o=&orig_cvip=true&rt=nc
