A few months ago Bud Meyer found the entire order of these C&S chips.

They were in Hertz's book of United States Playing Card Company records, printed in 2001 as CG. Fast forward to 2012 when I obtained a copy of the USPC records and was getting them ready to upload to the Chip Guide.

I saw no reason to doubt and in fact agreed with the CG on the chips. The C is dominant and the G is much smaller. Fast forward to 2013 when Bud found them. They were in the original USPC chip boxes with the monogram on the boxes. They were stamped GTC. Do you see the T? Sideways and very small. I considered a company logo but could not find one to match. IMO that leaves a personnel game set of 200 of 5 colors. How about Carl T Good? Good as guess as any.

I asked our "Friend Of The Hobby" to take a look. He found information on the H.S Crocker company that ordered the chips for resale but old GTC is still a mystery.

In the 1920’s the USPC processed several chip orders for H. S. Crocker Company, Inc.

Here’s a description of the company from 1929:

Here’s a snip from an ad from the 1920’s; they sold playing cards, dice sets, poker supplies (I’ve seen several USPC orders made by stationery companies):

An intriguing thing about the GTE order is that Crocker placed another chip order at the same time as the GTE—same number of chips, same colors.
The dual order might provide a clue as to who the chips were made for....maybe (I’ll have to look into it further).

My note: TN ordered same day as GTC.

other orders:

OK gang take your best shot. What are the above initials? The C&S boys are barred from guessing. I am pretty good at figuring out fonts, but I have to admit, I had to have help on this one when I first got the USPC records. First to post correct initials gets a nice FL illegal.

My note. As I have stated in the past, not all research turns up a bulls eye. I have a number of these misses that I will post from time to time. Maybe they will ring a bell with someone. IMO the only way to figure out the end users of most of the chips in this post is to find the H.S. Crocker records. Any of you CA boys want to take a shot at finding them?
