There were some questions on two chips of the Havana Riviera Hotel, the newest & largest, most luxurious Hotel in Havana and the creation of Meyer Lansky.
-There was a blue chips with a $5 denomination, only in one side, the back blank. And the decal was poorly attached with most chips having part of the decal or almost the entirely decal missing.
- In addition there was a $1 denomination chip with the same black color as the $100 chip...?

The whole set used on tables is below.

[The blue with poorly attached decal only in one side was used only on the opening day in the casino.
This was given to the VIPs to use them that day; of course everyone there on first day was a VIP.
That is why the hotel was not going to spend in two decals per chip and was not carefull with the decals as these were to be thrown away subsequently.

The black $1 was a back up/originally rejected color. I do not believe they were ever used. Practically all the ones found were brand new. This goes along with what the big collectors in Cuba believe based on the info those who worked in the casinos gave them.

This incredibly imponent hotel was Meyer Lansky's dream, his baby, his coronation!! Do you think anybody would be stupid enough to try to pull a fast one on Lansky?? in this hotel/casino which he personally supervised?? ................ NOT!
