The only two authentic Memellande medals, that I am aware of, that have a maker's mark is a slanted G type, "H.G." stamped on the rim and the L/11 by Deumer, L/11 stamped on the suspension ring. There may be other maker marked examples that I haven't seen or heard about. Not all slanted G types have the H.G. stamping ..
It has been proven, without question, that there were multiple manufacturers of the Memellande medal. And that these manufacturers produced both the slanted style G and the straight G style. (the G seems to be the starting reference point) It is also extremely important to only make comparisons between known "like" manufacturers. For example, you cannot compare an L/11 to an H.G. marked medal. Two different makers! You must always compare apples to apples and oranges to oranges to achieve any form of constructive accuracy. So comparisons of Ms, 9s or acorns between different manufacturers is a waste of time.
It's a common belief these medals were never cast, they were stamped (coined). This is "one" sure way to identify a reproduction.
Experts agree, to make an accurate determination of authenticity, you should have the medal in hand. Dimensions and weight is another factor.
The ones with the slanted G are popular because one with that style of G is "clearly" pictured in Dr. Heinrich Doehle's publication in 1943. "Badges-Decorations and Insignia of the Third Reich." Because of this they are widely accepted as "textbook" and the easiest to sell. I think the sell ability carries allot of weight here......... BUT ..... There are also known fakes with the slanted style G ..
With all of the research into the Memellande medal and the subsequent discoveries, we must rethink the old ways of authentication and open our minds to the new facts. During the Third Reich period there were, in fact, multiple manufacturers of the Memellande medal and there obviously was variation, between the different makers, in the fonts or styles of letters and numbers.
Rob, it is possible your Memelland medal is a good one. It seems to be stamped and not cast .. You might catch some flak about the "plinth" touching the rim .. There will always be a clash of opinion on these medals as there seems to be a distinct line in the sand between the slant G brigade and those with the ability to think outside the box.
Thanks to Uwe (speedytop) for your ongoing efforts.
All the best ..
