Very interesting, if I understand. Are both the copper-plated (1-pfennig) and brass-plated (5- and 10-pfennig) coins introduced 1948-50 descendants of these trials?

Hello villa,
Sorry for the late reply, I did not see your posting before today.
According to Jaeger trial strikes of both copper- and brass- platings where made using the dies of the war time 10 pfennig. I am afraid that I do not know if any of these has survived.
Perhaps anyone else does ?
Well, Künker Coins did. At least one specimen has survived and will be sold at auction on march, 18 :

One of the references in the auction- catalogue is pointing to " Die Probe der deutschen Münzen "of Rudolf Schaaf where the following is stated:
No 371 : steel, goldenplated, 1 speciemen known ( probably this particular one ), diameter 21 mm, thicknes 1,7 mm, weight 3,4 g
No 372: steel, copperplated, 20 spec. known, same diameter, thicknes and weight as above
N0 373 : steel, brassplated, 20 spec known, same diameter, thicknes and weight as above
No 374 ; steel, tombacplated, 20 spec known, same diameter, thicknes and weight as above
Furthermore,Schaaf includes a letter from the director of the Berlin MInt to the Minister of Finances apologizing for the most unsatisfying outcome of the trialstrikes. When the coins where thrown in various fluids, as sodium, different acids and
beer, they all got more or less discolourated ( copper and tombac altered less,hence the use of tombac for the postwar standard coinage ). In addition to this misery, the fact that the trial- coins where not coated but plated made the steel core rust rather rapid in moist air, wich together with the discolouration made the coins unfit for the use by native africans who, according to the Mint director, prefered shiny coins.
