DENMARKS first stamp, the brown 4 RBS (Rigsbankskilling) was issued 1. April 1851. The blue 2 RBS shown in the picture, was issued a month later. Its main use was for internal postage in the capital Copenhagen. There are two printings, the Ferslev printing and the Thiele printing. The Ferslev printing in mint condition is the most valuable stamp from Denmark with a CV of no less than 65.000 Dkr. (approx.. 9.000 $). The stamp shown has some quality problems. It is very close cut right, and has a couple of other small faults. Therefore it was sold for only 2.700 Dkr. (approx. 300 $).
