Well, I don't know, David. Your article though, says some were made by BudJones after the casino closed. Sounds like a reorder to me[g].

Having seen a lot of plastic coin inlay chips of different colors, I would be reluctant to try to differentiate two different orders by color. They do change considerably with time. They also can sometimes be darkened with oil. I've seen that with the Sahara Las Vegas $5's.

I'll say again, for a $20 chip, if you like Castaways you don't care whether Osborne or Castaways actually ordered the chip.
