Going through a pile of error coins to put up on ebay this week and came across this one. Figured since I had it photographed I'd post it for show and tell. Just doing a Google and eBay search for similar coins is seems as if these are not very common.
Thanks! The error lot I bought had 60 coins, and there was a little section with maybe half a dozen foreign off center strikes and a double struck Mexico coin. This one was the best, although one is one of those crenulated rimmed 1976 Philippine 5 Sentimos about 30% off which is really quite striking (pun intended) looking.
