Watch for re-perforation (to fake a more well-centered stamp), for re-gumming (a major problem with the Bank Notes), and even
for bleaching
of the cancellation (to remove the cancel). Unused copies carry a
substantial premium over the used stamp.
We include the "Special" printing, Scott 205C in this
identification guide merely for completeness. According to the Siegel
Scott 205C Census only 22 copies are known, somewhat
surprising, for it is thought that 2,463 copies were sold to the
general public. This is partially explained by William E. Mooz in an
article in "The Chronicle", February 1992. We occasionally see uncertified copies
of Scott 205C offered for sale at ridiculously low prices. You can
rest assured that the stamp being offered is not genuine.
