Upper left is the older Atlantis (Paradise Island - Nassau, Bahamas) chip which was in play until the spring of 2003.

Upper right is the chip which replaced the one on the left and hit the tables in the spring of '03. The most prominent feature of this chip was the orange colored inserts which began to bleed the moment they were put into circulation.

Lower center is the new $1 chip just put in play at Atlantis 2-3 weeks ago.

Sorry if this is a redundant post - I hadn't seen the new $1 chip posted yet.
