I just came across a 1920 Aachen 10 pf coin that does not seem to be in the catalog (not in Funck either). It is a nickel plated iron coin that seems to correspond to F1.4 (it is medal alignment). So far so good, BUT it also has the error of YERSONK (Y instead of V).
Or perhaps it is F1.3B with medal alignment(not listed in catalog)?
