I don't know what site that is.
www.chipco.com goes to GameOn Chip Company's site, but that doesn't appear to be it. That said, GameOn doesn't appear to be selling to the public, either.
My understanding of the history of Chipco
- Sold custom ceramic chips to the home and casino market. Blanks known as Protech.
- closed in the early 2010's (2012?)
- assets bought by PGI
- some ex-employees formed GameOn (GOCC) using very similar blanks. Looks like GameOn acquired the rights to the Chipco name at some point.
- GameOn left the home market.
- PGI closed a few years ago (2017?). Assets purchased by ABC Gifts and Awards.
- ABC as restricted the Protech blanks they have...they are no longer available to the home market.
(I think the above is correct, or at least close)
All told, "Chipco" chips are not easy to find, except on the used market. GOCC's are very close, if you can find a set.
That said, one of the vendors here (Holdem Poker Chips) have some from closed casinos on their pages (
