Oldenburg - Briefe 1855
Katalog Michel 1
Oldenburg, 1855, First Issue, 1/3 Silbergroschen black on green paper, spectacular strip of three, showing some almost invisible repairs, cancelled by rare straightline handstamp "LANGWARDEN" in blue on beautiful folded cover to Elsfleth.
A very rare multiple of the # 1 of Oldenburg on cover; this stamp was normally only used as single franking to pay for the printed matter rate, here it was exceptionaly used as strip of three to frank the inland letter rate of 1 Silbergroschen.
Michel 1 = 20.000 EUR (for a strip of three on cover)
Certificate Florian Berger BPP
A similar cover (but in perfect condition) was part of the famous Boker collection (ex Caspary), it sold in 1985 for 88.000 DM = 44.000 EUR (including buyers premium) see scan of this reference.
