10c Green (226). Full top right imprint, plate no. 28 and letter "E" block of 21, the plate block of twelve Mint N.H., five stamps lightly hinged, deep rich color on bright paper, few minor perf separations sensibly reinforced at far right (not affecting plate block)

FINE-VERY FINE. AN EXTREMELY RARE BLOCK OF 21 OF THE 10-CENT 1890 ISSUE, WITH THE PLATE BLOCK OF TWELVE IN PRISTINE MINT NEVER-HINGED CONDITION.

We have offered only four plate blocks since keeping digital records, including two from the top and two from the bottom. For the other two top positions contained in Power Search, one is missing the "No." (so technically is not a full plate block) and the other is a plate of ten. This is the first from the top position we have offered in Mint N.H. condition.

Ex Wampler. With 1988 P.F. certificate noting only one stamp previously hinged. Scott Retail as plate block of ten and singles
