Sorry for the delay in responding & thanks gavin-d for your comments....so difficult to find with these old Sudetenland overprints! My reasoning was simple: I've purchased from almost every one of these dealers & out of a total of almost 80-auctions, ALL were forgeries, hence my comments. Toner ink forgeries have become the new norm on "ScamBay," I published an article on how to spot this new generation of fakes. While the photos appear genuine, even up close, they are taken "head-on" not allowing anyone to see the glistening of polymers & metals in the ink. These forgeries are easily overlooked from the listing photos but are obvious in sunlight with a loop. My point was simple, NONE of these photos can be relied upon for determining authenticity. Unless the stamp is in-hand it's virtually impossible to make any judgement. These forgeries take all of the idiosyncrasies of ink markings & use them in scanning technology to "re-print" them onto stamps, even over existing cancels. The "Maffersdorf" cancel is in the new set of forged cancels & is being used along with "Wir sind frei!" overprints including colors, even the colors of "Karlsbad" overprints. Colors are another issue with water-based inks being used. These were NEVER in use by Germany (as ALL inks were permanent oil-based) & will come off with nothing more than a damp cotton swab. (see photo below) I wanted to illustrate the ease in which these forgeries are being manufactured & how simple it has been for "ScamBay" to NOT police their auctions & let literally thousands of these deliberate fakes come to market. Photos MAY appear authentic but the use of this new tech can fool even some of the best collectors & dealers.gavin-h wrote: ↑25 Jan 2021 02:26I have to take serious issue with your statement "Basically, anything "Sudetenland" is a modern toner ink fake" and some of the images you posted are also not immediately obvious fakes.
That is certainly not the case. I have been collecting (genuine) Sudetenland covers and stamps for many years, and saying that is doing a great disservice to many legitimate dealers and collectors of this very interesting area.
To look at the examples you illustrate above:
1. Difficult to tell although the shape of the swastika is not quite as I'd expect to see it.
2. The cover and the Maffersdorf postmark look fine. The illustration of the overprint is too small to give a valid opinion.
3. I'm inclined to think this one is OK, the "compartment line" at the foot in the same ink as the overprint is usually a good indicator.
4. Illustration of individual stamps is too small to give a valid opinion.
5. The postmarks on this look fine and match closely to what one would expect to see. Clearly philatelic / "to favour" cancellations but I'd be happy to own this.
6. These are clear and obvious fakes. A selection of random, earlier Czechoslovakia issues, some with clearly visible Prag, Brno etc postmarks are dead giveaways.
7. Without clearer illustrations I wouldn't like to give a definite view, but possibly a fake as this overprint is uncommon on values other than the lowest 3pfg.
8. Again, too small to give a definite, but the tete-beche arrangement is unusual, to say the least. I would be suspicious of this without a certificate.
9. Too small to see clearly but I would be suspicious of this lot.
10. Almost certainly a fake, there is no record of such an overprint. The fact that the Hitler definitives weren't issued until 3 years after the annexation of the Sudetenland also points to it being a fake.
Clearly the message is that if you don't know what you're looking at you could get your fingers burned so best left alone. But please don't dismiss everything out of hand.
Thank you for your detailed analysis of each listing. I can assure you that every one was fraudulent & that every dealer I listed has both genuine & forged stamps & cancels. I want everyone to have some tools in their toolkits as these examples are indicative of printing tech being used at ALL LEVELS & on every type of stamp. One forgery is one too many. All of these just add-up to deception & "CAVIAT EMPTOR."
