Theyre real, but very very rare, so nothing is really known about them (obviously).
They are blank back very thin stock, 1-1/2" by 2-5/8" machine cut.
I picked up the Rommel on eBay about 9 years ago for $5 from a lady who wasnt a collector (she had it pictured on a doily, lol),Its basically NRMT+/MINT.
The Hunt lot of 6 sold for $1200, and the Hornsby (lowest grade one known) now at $300.

Obviously not many have handled them, not sure who owns any of them now, I sold the Rommel years ago for a few hundred, and I know someone here or on an old message board picked up the Hunts lot.
Thats all the info known.
