The only game I've ever seen or heard of is a 6/12 poker game, using $3 dollar chips. The club is not going to invest $$$$ for a game that's not going to be played except for a few players. 3/6 , or 4/8 , or 10/20 , the latter YES , OH !!! YES.
BUT, I have seen costly avenues come and go. Example $6.66 chip.

Please clarify if it is a ZzX chip or a $6 dollar chip.
