I believe the Prescott thrift shop find included one used '50' with the '10' chips, according to what the finder told me... and, yes, the '50' still is (thus far) the most common in the series with 101 recorded pieces known.

I'm glad to hear there are still only four of the '1' chips recorded.

I wonder if there was a wheel in the room and, if so, were the chips other than generic.
