Between a 2 and a 4 yr old and a job, I'm lucky to get to play once a week. So it is not from over use. Mine symbol was painted on, I could take it off with my fingernail(just tired on 2P) because it now looks like a plain white button. I also bought it from Starburst Coin Machines who is a distributor of Happs products in Canada, so it was from a reputable source.
