Luke, the gray "JS" $1.00 chip is from the Lake Bowl in Folsom, Ca. JS stands for the owner, Jack Sessions. Although the Lake Bowl card room is open sporadically (sometimes one evening a week or so--so I've been told,) these chips have long been gone and haven't been in use for many years. I do have a blue or possibly a green chip from the same house that I would be happy to trade with you if you have another gray.
