Dan, the right side of your stamps has
a normal straight edge, which would have
been created when the larger sheet was cut
down into smaller panes. I am guessing that the small
arrow in the bottom right corner is part of the
cutting guide from when the full sheet was printed.
The left side looks like someone cut the perfs off of
it. The side slants down from the top left to the
bottom when I view it. I can not think of any reason
for the PO to issue coil postage due stamps as they would
never be loaded into a coil stamp dispensing machine for
public purchase.
