The El Tropical was a real venue in San Juan, Puerto Rico. Opened 1992, Closed 1999. Keep in mind that San Juan casinos are typically barely bigger than a postage stamp. I do not expect to see these chips in large lots, they didn't need that many chips to operate.
I'd say the set is playable with a $7,400 bank for a $1/$1 game and many $1/$2 games.
These are chipco, so nothing as valuable as Paulson etc. Even so, I think $0.50/chip seems reasonable - or $250 for the set.
I'd pay $250 if someone offered them up to me -=- DrStrange
