Today we have added 2R3.4 to our listings. Guy Jeffery provided 3 examples of a nice re-entry at the bottom of the stamp and one was dated.
Today Guy provided a scan of a registered domestic 1874 cover which provides us with the first date for 2R1.1 ~ Aug. 29, (18)74. He also sent along two scans of a strong flaw in the left '2' of a 2¢ Green, which is listed as 2F1.5. These are the first examples of this CPV that I have seen, but it is likely that it was previously reported by Ron Waldston as "2PF 829".
I received an email from Guillaume in which he shared a new constant variety on the 5¢. Guy and I got busy trying (unsuccessfully) to find additional examples. Check out 5F2.1. During our search, we managed to find 2 examples each of both 5F1.5 and 5F2.2. The latter is most peculiar and warrants further study.
