Larry Trapp turned up several boxes of these years ago, the find included BH white and blue, along with the fancy KD hub mold chips. There were also some green small key chips with just $1.00 on each side, and some red with 2 green 1/4" insert, $10.00 chips, also with no other markings. I know at one point Larry was selling all these chips for $5.00 each.
