This coin is pretty rare as I have only seen this one coin. The banner sticker for this coin is the common banner, but contains a rather unique landmark. While I would much prefer to have a perfect sticker, this coin in my eyes is highly collectable.
I would love to know the history of this coin. I’ve done some research on the town of Massadona and I don’t believe the town currently exists. The closest town from Massadona is Dinosaur Co, which is about 20 miles away. I think that back during the 1950s there might have been a gas station/camp ground that might have created these coins as a way to advertise.
