Gene’s earlier thread on Borland chips spurred this question.
In 1968 Walker Hill Casino was the 2nd casino that opened in South Korea.
Are these Borland chips? They are not coin aligned.

How about this one? Olympos Casino was the first casino in Incheon, South Korea that opened in 1967. It has since changed its name to Golden Gate Casino. This chip is not coin aligned.

I believe these chips are pre-1991 (pre-Borland).
Thanks for any help.
