I might be partly responsible
When the rack was sold (April 2005) Spinetti offered $1m for the lot and was turned down. We did have a count on some of the chips. I recall there were 23 or 33 racks of this $25. Gene, does that sound right? I remember we were on a cruise to Mexico
Some of the matching $5's did get out to the public at the same time (many appeared in 'slabbed' sets later. I bought some at $3 each, I should have bought more
I guess one of us gave Allan the numbers and he based his values on that.
