One day while attending my table at an earlier convention of ours, someone walks up to me saying... "I have a chip like that (pointing to my 50s), but it's a 25..." It had two mounting holes.

Later, the chip was sold at a private auction for $705. It was the only one known at the time (except for the one in Howdy's photos).

I think the "1" still remains the rarest of the lot; while 4 examples are known in their original state of preservation and two being drilled.

The first of my four "1" chips sold for approx. $600 and the next at $1000, then $1750 and the last at $3000.

I, too, have not seen or heard of any other "25" examples being offered.
