Hi IP. 100%?? Well noooo. Here is a pic of the back. Maybe that will help confirm or not? Also it weighs about 4g and is about 32.76mm. Thanks again for looking!
Ok, I just wanted to eliminate countermarked coin, and I actually would have bet before seeing that pic it was probably a counterstamp. That's a very cool button but I can't offer any help and I'm not sure anyone else will be able to either. It's very different.
haha, my son said he sees a turtle with a squid on his back. pretty funny
