German Allied Occupation Private Issues

I am not sure if somebody can help here. I have few series of German local stamps and I suspect some of them could be forgery (just based on relatively high price for genuine stamps of this type).
Also I cannot find any information on some of them.
For example, I have attached images for few varieties described in Michel as "Mindelheim and Kirchheim" #2. Stamps even have BPP marks on the back. Are there any experts in such stamps? Genuine or fake?
And also - what about that "blank" stamp without price? Michel is not mentioning anything like that. Thanks

igopp,

Michel catalogs the post-1945 locals in two ways -- those that were "official" in that they were available at the post office, and those that are "unofficial" or "private" in that they weren't produced and provided by the post office. The unofficial issues were frequently allowed for use as valid postage because the entire system was in chaos until the Allied governments got the system back up and running.

This is why you you can't find the blank issue with MiNr 2 -- it's listed in a different section of the catalog. The one without a value is MiNr 1, the "official" issue for Mindelheim, and MiNr 2 is the "unofficial" issue.




This isn't my area of expertise, so take this for what's it's worth...

The GPS Forgery Manual lists a couple forgery types of these, but they don't match your copies. The forgeries tend to be of lower print quality, and yours appear to be of the same print copy as the originals.

As to the BPP marks, Sturm used to be the expert for these. I'm not familiar enough to tell you whether the marks are genuine. For many of the BPP expertizers, they used multiple marks over the years, so there's no one true mark for an expertizer. If you look at the marks listed on filatelia, at least one of the marks matches a known legitimate mark, and at least one matches a mark that is known to have been forged.

The BP lists one curent expertizer for these -- Jens Kurz.

Postmaster - thanks a lot! I found "official" description, but still wonder if there is any value in "blank" unused stamp. I am not sure if it is interesting for anybody else, but I can post later few more images of local stamps that I cannot categorize. Thanks again and specifically for links to Expert Signatures. Unexpectedly in my latest acquisition I have quite a few stamps with BPP marks.

Even though Michel doesn't list a mint price for MiNr 1, there's still some value in it.

Here's a pair of mint MiNr 1 that recently sold for €85.

I have next sample of local stamps - Demmin.
It seems that they match description of #3 and #4 (local issues 1945).
Also cancel date is in the range described in Michel (circulation period from July 11 to Aug.1, 1945). However - I do not think those stamps have been postally used. They are just too clean and almost perfect. Also each one is only partially attached - I can tilt both stamp slightly and see most of gum intact on the back side.
Postmaster - what do you think?

Have you checked the dimensions and the perfs? I haven't been able to find many images of legitimate copies to compare them to.

Yes -
Dimensions: 20.4x12 mm
Perforation 11 1/2
Everything as described for type "b".
There are more similar Occupation stamps in this collection: all with the same type of "partial application" (by only small part of gum) and very clean cancellation.
For example I have image of few stamps from large Fredersdorf series and also image of back side (to show intact gum). Actually those stamps are very suspicious. All with the same cancel date: July 26, 1945 and cancellation is missing asterisk (comparing to image from Michel).
