The group that is on the Chipguide is complete. You can also check the latest TCR but I've tracked them pretty well (being a fan). They did them for a couple of years to coincide with the ST convention.

2002 - 1 chip
2003 - 2 chips (kirk/spock)
2004 - generic chips, not casino released (not in chipguide)
2005 - 11 chips
