There was a recent purchase of an entire rack of the 25’s I heard for 20k from the same seller of that eBay one. So there may have been 2 boxes. Odds are you will see them pop regularly now. I was also told that the deal with the 25’s was 2 or three different $5’s from the same era. The $25’s I hear were originally sold for $2000 a rack so to pay 20k and probably told it was the only one could be a bit concerning. I mean the cotton clubs were selling for 2500 too and now 280 have surfaced. What a hobby.
