This stickered coin looks to be a slot machine payout coin for an unknown Casino. The image is either of a burst or flower pattern and has 8 petals. Judging by the sticker it looks to be from the 1950s or early 1960s.
This coin is in great condition and the sticker is completely intact. I own several of these and have seen a few show up on ebay. By far this stickered coin is in the best condition I have seen. Most of the coins I have seen have heavily warn stickers and coins from years of passing through slot machines.
Only a small percentage of stickered coins use a transparent sticker, which is one of the things that make this coin unique and highly collectible.
Most likely a casino slot machine coin.
