What is this Las Vegas dollar 1878 a copy that has something to do with the convention center A lot of casinos named on coin are closed Know anything about coin?

There is no such thing as a Las Vegas dollar 1878 coin with casinos named on it.

Las Vegas was founded in 1905, and the only dollar coin minted in the United States in 1878 was the Morgan dollar, which does not have anything to do with Las Vegas or the convention center.

The casinos that are named on the coin are all closed because they are fictional casinos.
