I recently purchased 5 chips of which none are listed in the 1998 Edition of The Gaming Table, Anyone know why?

1. Annie Fannies Casino - Spokane, WA
2. Billies Casino - Des Moines, WA
3. GoldeNugget Casino - Shorline, WA
4. Grand Central Casino - Lakewood, WA, and
5. Casino Fandango - Carson City, NV

Any info would be appreciated.
