Hi all. Is the top of this stamp caused by the sheet being misaligned or is it something else? Also, how would this effect the value? I am still fairly new to this and still learning. Thank you in advance.
You have a coil stamp which was cut at the top and bottom by an affixing machine which was slightly out of adjustment to coincide with the perforations. Note the slight uphill slope to the cuts as you look from left to right of both cuts. Most collectors would consider this a damaged stamp because of the cutting, but some see it as evidence of the technology of the era.
The stamp looks like a type III 450. While faint, the second line in both ribbons can be seen and there is no vertical gap under George Washington's ear. The larger perforation holes were characteristic of 449, 450, early 489 printings and possibly other early rotary press vertical coils.
