Incredibly scarce broken'O' (in a pair) on a mint stamp.. The broken'O' variety is much more scarce and should command a price commensurate with it's scarcity... See the Salz realization below..
30c Lake red, 19mm overprint, "O" over the "N" variety, a seldom seen mint single, rich color, o. Never hinged, diagonal gum bend, very fine; while used c. Example of this variety can be found with regularity, mint copies are quite elusive (CZSG #CO5.2a). I have added a nice selection of many stamps to my store.
I fondly remember going to stamp shows as a child, enjoying going through counter books where I could pick out the'ideal' stamp for me. The days where local stamp shows would allow this experience are few and far between. I have attempted to re-create this by listing selected stock which you can pick from.
