Mr. Finger--I have some info on that pattern coin:
As quoted by Mr. Kurt Jaeger of Stuttgart, the eminent German numistmatist:
"...Quite different however, is the case of a Hitler pattern 5 Reichsmark of 1942, Mintmark A, copper, silver-plated, which was struck in normal size and with the customery edge engraving of the German 5 Reichsmark pieces in Berlin after a design by the medalist Goetz.
One piece was presented to Hitler in his headquarters Wolfschanze by the Director of the Monetary System in 1942, Herr v.P. As the widow of Herr v. P. vouches, Hitler said about the presentation that his head should appear on the German coins after the final victory. This pattern is still in existence today in the above mentioned hands.
A total of 4 pieces were struck...."
