I have just found a new Die Clash Error from the New York New York with Babe Ruth Bust with signature and S mint mark. The picture show the clash on both sides at the ears, and I can't find any NY NY strikes that have the clash outline, so it may be clashed with a different casino back die. This is the first one known to my knowledge, and may be the only one. It will be listed on Ebay today with many other strikes, so don't miss the chance to add this rarity to your collection.
