These were brought back by my friends Mel and Lisa Jung from their fantastic cruise around the tip of South America.

About the orange plastic chip, Mel says:

"CM was Montevideo Uruguay and each color used for peso denoms like 100, 50 20 etc. I forgot what colors for which chips,,....sorry. Yes, Casino Municipales."

I thought the other chip might be a "game chip" for the punto y banca game, where the P might indicate a bet for Player (or punter), but Mel says that's the name of the casino.

About the yellow chip, Mel says:

"Punto y B was the name of the casino in Puerto Madryn and were used for US denom play. I had to play to get the chips and it was a disaster since I had no experience in their rules and payoffs.....minimum was like $4 US and it cost me $50 to get about 8 chips because no one spoke English or ....Chinese......
Chips were used in Blackjack and plastic wheel chips with high denom plaques......French Roulette which I hate to play since I never learned the payoffs etc....and its a dumb game.....the plaques started at about $50 US so I did not try...."

About Buenos Aires, Mel says:

"The only casino I could find was in the two paddlewheelers moored in the harbor. Each was exclusive US Dollar or Argentine Peso play. Each had their own slots and coins .....and buckets. The ones like the 2,5 with comma were used as US Dollar chips. The others with dollar signs were pesos on the other boat. I found one other casino near a large park called the Rojo Parque and it only had slots...."

I had no idea there were so many casinos in South America... just looked at a web site on Argentia and there are dozens. I'm not sure I'd want to play at some of them, but getting chips would be nice!
