I picked up these GHYAC chips a couple years ago In Centralia, Washington. They were in an antique shop and they had a very large number of the $1 and $5 chips. Just a few 50 centers and only one $10 chip. I was given an ID as being from the Gig Harbor Youth Athletic Club. Is anyone familiar with such a place. Would they have been a private club, illegal, card room or charity chips? Thanks in advance for any information.
