Klein advised Green that the stamps would be worth more separately than as a single sheet, and Green went along. He donated one invert to the Red Cross in support of its war efforts (which was auctioned off for $300), while retaining forty-one of the stamps in his own collection, including the plate-number block (initially eight stamps) and several blocks of four. The remainder of the inverts were sold off at steadily increasing prices through Klein, who kept a block of four for himself. Green had one copy placed in a locket for his wife. This gold and glass locket displayed the inverted Jenny on one side, and a "regular" Jenny stamp on the other. This locket was offered for sale for the first time by the Siegel Auction Galleries Rarity Sale, held on May 18, 2002. It did not sell in the auction, but the philatelic press reported that a Private Treaty sale was arranged later for an unknown price.
