EXTREMELY FINE MINT NEVER-HINGED EXAMPLE OF THIS RARE ROTARY-PRESS PRINTING.
At the beginning or end of a coil-stamp print run from the 170-subject rotary plates, some leading or trailing paper was left over that was too short for rolling into 500-stamp rolls. In 1919, the Bureau devised a plan to salvage this waste by converting the stamps from coil stamps into sheet stamps. This was accomplished by cutting the sheets into panes and putting the panes through the flat-plate perforator in use at the time, giving the stamps perforations on all sides.
Since Scott 539 was put through two different perforating machines of differing gauges at different times, most of the stamps are off-center. The stamp offered here has remarkably choice centering and ranks among the finest of Mint N.H. examples.
