If you are planning a trip to Las Vegas next year the Convention will again be held at the Tropicana May 30 through June 2nd. On my site I buy, sell and trade not only chips but also other casino memorabilia such as old matchbooks, ashtrays and linen postcards. With only 2-3 known, this is a very special chip. I bought the chip from the person she sold it to. You don't have to collect high value obsolete chips.
People collect differing denomination current chips from all over the world.
In addition to current or obsolete house chips, limited edition chips are VERY popular. These LE's as they are called by collectors are made for special events, holidays, grand openings, sport figures and so on over the course of a year. There have been a number of LE poker related chips made over the last 6 years. One of the most popular is the 20 chip set made in 1994 by the Horseshoe in Las Vegas. Chris Ferguson will of course be pictured on next years newest addition to the set.
