The hologram center tokens that have been issued in Nevada for the past two years are made by Osborne Coinage and have nothing what-so-ever to do with Silver Strikes or IGT.
I have no knowledge of the token from Aruba, but am willing to bet it is not from IGT.
As was mentioned the rules in Aruba are much different than ours. There are still places where one can find 1967 Franklin Mint Nevada casino tokens in play in slot machines
