Linn's is reporting that the 24th upright Jenny sheet has been discovered. A collector from Arizona purchased it from the Stamp Fulfillment Center in Kansas City. He and another collector had purchased about 1000 sheets before finding the upright version.
I don't think he's going to sell it. At least not at this time. He is working on a philatelic exhibit on the sheet with all the varieties from the printing. The upright sheet will be the crown of that exhibit. Maybe after he displays the exhibit at a few shows he'll sell it. He'll definitely get his money back.
It's been quite a while since the last find was announced.
"I bet he'll lose points because some judge will say the exhibit is not complete without a 1918 Inverted Jenny!"
A friend of mine once exhibited a fabulous collection of Occupied Malaya postal history. He got a vermeil medal, not a gold, because he didn't have one representative cover, which he could have bought, if he could afford it which he couldn't, for only $2,000. To me, that seems nothing less than prejudicial. Under the same "rules," I suppose that a collection illustrating the history of postal errors wouldn't get a gold medal if it didn't include Mauritius "Post Office, "Treskilling Yellow," and "Inverted Jenny" stamps, not to mention dozens of others.
I have, fortunately, worked with many judges who are intelligent, common-sense people who have reasonable expectations about exhibits.
"The Mauritius Post Office issue was not an error."
Good to know! Now I won't have to buy one to complete my collection of philatelic errors! But, seriously, I didn't know that. It certainly seems like an error!
