One of the vendors at this year's Spring Jamboree (car show, food truck extravaganza, arts and crafts show, and antiques/collectibles faire) had these. I managed to get these chips, along with 95 or so $1 slot machine tokens, as a single Lot.

Gotta love the 2 Aladdin chips. Got both the red and pink versions! Whoo hooo!

Thanks for looking!
