If you're into collecting playing card stamps, you've probably come across the large "Class A" stamps.
These are listed in Scott with a number of different perforation varieties: imperf.; roul. 14; roul. 13 in red; roul. 6 1/2; perf. 12 vertically; and perf. 12 on four sides.
In the next-listed section though, there is yet another one.
This one is roul. 9 1/2, with a variety of surcharges.
And finally, the one listed as "surcharge omitted" is shown below.
A truly uncommon stamp.
