1. We don't know how many of the same monogrammed chips went to who (no matter what they advertised)...

2. There are many instances where more than one monogram (same lettering/graphic) was used at one establishment... and research shows us even two different monograms can be used on the same chip; obverse and reverse, of which neither is even a close match to that establishment's monogram found on their stationary or stock certificate.. and more. Meaning, one joint could have had a few monograms over a period of time.

Just one example, here: one chip, each,
with two monograms.
