In Nevada, I have 4 groups or groups of albums:
Las Vegas, Reno, Lake Tahoe & Other Nevada.

The first three groups have the chips alphabetically by casino name, then non-denominational, followed by smallest denom first, to the highest. The Other Nevada albums are alphabetically by city, with chips the same order as the first three.

Other U.S., I group by States, City, Casino & denomination.

I group Riverboats & Tribal Casinos by State, City, Casino & denom., one album for Riverboats and one for Tribals.

I group foreigns by Country, City, Casino & denom.

I keep my Crest & Seals in separate albums by club-casino name and generic poker chips by Seymour categories.

I have Unknowns in alphabetical order by what is on the chip.
