I recently did a bit of a road trip through the South of Chile and Argentina, and picked up chips from 3 small casinos. I offer some spares here for collectors. These chips are off the tables, and I'm pricing them just slightly over face. Add $5 for shipping from Chile using a tracking number and a bubble mailer, no matter how many chips you want from any of these postings. (This is my actual cost - I don't gouge on shipping.) Expect delivery to US addresses in about 2 weeks because of Chilean donkey-mail.

Casino Puerto Varas is mostly slots, but has about 12 table games, including roulette, blackjack, and a strange Caribbean Stud Poker variant. It was a pretty 'happening' casino, with live music.

500 Pesos chip just posted for completeness, I have none available.
1000 Pesos chips are $4 each (I have 7 available)
5000 Pesos chip is $18 (I have only 1 available)

They also had 10,000 and 20,000 chips, with plaques at the 50,000, 100,000 and 200,000 denominations.
