Fake Or Real?

Hi, I'd appreciate anybodys help identifying the attached stamps. Looked them up in the Michel catalog and all seemed OK, I just can't believe that I have that many of them if they are real, Thanks...............Pete

Wäre Euch allen sehr dankbar wenn mir jemand bei der Identifizierung der beigelegten Marken helfen könnte. Habe schon im Michel nachgeschaut, aber es kommt mir etwas komisch vor das ich mehrere von solchem Wert gefunden hätte. Vielen Dank.............Pete

Look kosher to me.

They all look pretty legit.

Deutsches Reich Mi 26 (7 Kr) -- no forgeries listed in the GPS Forgery Manual. Almost certainly genuine.

Deutsches Reich Mi 30 (9 Kr) -- no forgeries listed in the GPS Forgery Manual. Almost certainly genuine.

Deutsches Reich Mi 37 (2 M) -- no forgeries listed in the GPS Forgery Manual. Almost certainly genuine. There's almost no way to know whether it's an a, b, or c without sending it to an expert. Judging by catalog value, more than likely an a or b.

Württemberg Mi 36 (1 Kr) -- only forgery listed is an imperf, so almost certainly genuine. Can't speak to the cancel, as they are commonly forged and German States are outside my area of expertise.

Württemberg Mi 37 (2 Kr) -- no forgeries listed in the GPS Forgery Manual. Almost certainly genuine. Again can't speak to the cancel.

Completely outside my fields -- Are some of these worth a lot?

If there's gum on the mint copies, most catalog for at least €40.

Thank you everybody so far, Just two weeks ago I became the owner of a box of basically all old German stamps.(Auction) From German States, the Empire and up trough the Third Reich, Now I'm working with the Michel in one hand, the Scott in the other, sorting through the box. There are whole sheets of Hindenburg, Hitler, Flugpost, and too much more to mention. My guess is that I will have quite a few questions in the next few weeks. Again, thanks....Pete

If you have any complete, intact sheets, I'd be interested in seeing them.

Ask away on any German questions. The States are before by time, but the rest are in my wheelhouse.

To PostmasterGS, there are quite a few of entire sheets. What would be the best way to make them available for you to see? Greetings from HOT TEXAS......hawkstamp

Can you scan or take a photo?

They have all been scanned. There are about 25 sheets plus 4 or 5 that were separated in half at the perforation. Some are oversize, Flugpost, higher head values and Germania. I also have the special Hindenburg and Hitler "Elferstreifen", officially defaced Hitler heads, the special block of 4 Hitler heads with surcharge, issued at the NSDAP convention in Nürnberg, My intend is to sell all and more of this material, since I don't have a personal interest in the subject.

Let me know the best way to make them available for your viewing. Pete
