I have one of the chips that is #51. It's the only chip that I have that's very low. The rest were 300's, 400's and 700's.

I've only recently been collecting (within the last year) but I've already built up a small collection of 100 chips (all released within the last 5 years) but have started working on picking up chips from the 50's and 60's. Had what I hoped would be a stealth purchase on eBay for a Dunes (with the sultan/harem gal) $25, but someone else spotted it and blew past my max bid (which was $100). Ah well... can't blame me for trying and hoping no one else would realize it.
