Fatt's was a card room located on Monument Blvd. in Concord, Calif. up to maybe 5 years ago which then relocated to Clayton Road, Concord. I'm not sure if they are still active as a card room or just a bar now. I have played there back in the lowball days and to my knowledge never knew of any high denom chips. I can ask some of the 'ol timers that still play locally if they recognize them. I'm sure it will spark many stories of long extinct cardrooms in this area.
