"The green star and cresent chips I have came with a somewhat large qty. of Yorkshire chips. ???"

Lets say yours was used at The Yorkshire.
Lets say the ones Larry found were used at the Lookout House.
Lets say both places bought 300 each of 7 colors for roulette. Total 2,100 each place.

These chips were sold in BC Wills retail store for years. To Illegal casinos and for home games. 10's of, 1000's of them.

What I take issue with is telling a guy that found a couple in an antique store in Michigan or Iowa, that his was used at the The Lookout House.

People should know the truth about their chips.
