txstamps and classic coins --
Regarding the ex Chase photo stamps and how I came to acquire them -- all I can say is that it was pure luck.
When I first discovered that I had stumbled upon a number of these stamps, I attempted to research what happened to the Chase photo stamps after his death in May 1960.
I learned that the Chase platings were sold intact as a complete set in a Samuel C. Paige auction held on December 8, 1961 (lot # 14). Fast forward to October 21, 2010 -- Siegel's sale # 996 of Wagshal's 3c 1851 -- 1857 collection -- lot # 3003 in that sale was described as the Chase / Card plating -- and the lot description stated, in part, that Card purchased Chase's plating and then spent years improving upon it. If you closely examine the extract photo in the Siegel sale catalogue -- picturing the top half of the left pane of plate 1 early -- there are a handful of ex Chase photo stamps included. And, no I was not the buyer.
My guess, and this is only a guess, is that as Card upgraded (and also remounted) the Chase plating, he either sold off or traded away those stamps he did not want -- and that over the years these stamps have, more likely than not, scattered widely among 3-cent collectors.
Unbelievably, the 2 stamps I posted earlier this evening from plate 1E were found on eBay
-- and the 2L stamp was part of a trade with a fellow 3-cent collector. I also stumbled upon a number of these ex-Chase stamps in a bulk 3-cent lot I purchased around 6 years ago -- but until recently when I started to confirm some of the plate positions, I did not even know I had them. You can imagine my surprise when I went to compare my stamp to the stamp in the Chase photo -- and realized that the stamp I was holding in my tongs was, in fact, "the" stamp in the Chase photo.
Again -- pure luck.
