HISTORY AND COMMENTARY
Original-gum and unused blocks of the 30¢ 1861-68 Issue are extremely rare. We record two unused plate number strips of four: the strip offered here and another that emerged in 2012 with the sale of the Frelinghuysen collection (Siegel Sale 1021, lot 220). There is also a plate block of eight with "Specimen" oveprint. This strip was reduced from eight to four stamps.
