The Top Hat sticker dollar is quite rare and is believed to be a casino slot machine payout dollar. This is the only one that I know of, but I am sure there are more out there.
Note:If you have any more history of these coins or a story about these coin please leave a comment.
Note: This is a good example of a coin being rare, but the price not following. The lack of history with this coin hurts its value. This coin at auction could fetch a very large premium if the right bidders were involved. What is interesting about the sticker is that it is quite sticky, which I believe lends to its rarity. I believe most of these stickers were taken off and the coin cleaned because of how the sticker aged. This coin is sealed in an air tight holder which will keep this sticker permanently intact.
