First I apoligize for my wording in my reply to Travis. I guess I typed without thinking.
"It is a good story but more than likely BS."

Should have read, the story without facts is just a story, or words to that effect.

Your chip is not rare. I have seen them before. I am sure others here have also seen them. Using the rare word only detracts from the story.

Your chip was sold from the BC Wills Company that was in Detroit.

SMALL KEY (SM-KEY) (a/k/a SMALL GREEK KEY) -- greek key design, repeated 30 times. B. C. Wills & Co., Detroit MI and Reno NV, which made these chips from 1937-1965. No order/production records exist for the imprints.

I replied to your email.
