Dear subscribers, I would like some information regarding this stamp. For example, why the print is rotated and how much it could cost if I wanted to sell it. I would like to add that the stamp comes from my grandfather's collection. Thank you

Can you show us the certificate that comes with the stamp? Leon

@ MS Sammler [#2] Caro Leon, unfortunately I don't have any certification, but I would like to have one. As I wrote, this stamp was in my grandfather's stamp collection, most of them were Polish stamps and among them there was a German stamp about which nobody can tell me anything.

@ Malgorzata [#3] Fake overprints on the early Berlin issues are to be expected. If I have to judge the color and the impression, I would assume that you have overprint forgery. If you want help, a 600 or 1200 dpi scan would be very helpful, a blurred mobile phone image is not helping. There are two Berlin experts at the BPP: Andreas Schlegel and Hans-Dieter Schlegel [1] If you need an expert opinion, please send the stamp to one of them. The costs are: - Your registered letter - Your insurance - Invoice + VAT + registered letter (around 35 - 40 EUR) if overprint is fake All the best, Lars [1] https://www.bpp.de/briefmarkenpruefer-des-bpp/

@ Lars Boettger [#4] Hello, Thank you for the advice and, as you suggested to me, I'm sending better photos. Yours faithfully, Małgorzata
