Jesse, The Oregon Blackjack chip is indeed what Don Leuders says. It was a floating game up and down the Oregon Coast which closed in the early 1990's I believe. I Paid $60.00 for this chip and the $10.00 blue combined. I also own the .50, 1.00, 5.00, and the 150 years of the Oregon Trail 5.00. Wish I had more if there were more. Nice chip.
