VERY FINE AND CHOICE MINT NEVER-HINGED TOP PLATE BLOCK OF THE 2-CENT 1923 ISSUE WITH 6-POINT STAR.
In an attempt to improve centering, the Bureau began using plates with wider spacing between the stamps. However, to take advantage of this, they had to modify some of the perforating machines. Stars were added to some of the wider-spaced plates for rapid identification of those sheets bound for the modified perforating machines. At first, a small 5-point star was used, then a large 6-point star and, finally, a large 5-point star. The latter is common, but the other two are very scarce.
