 FACT: Maitlands German bonds are incorrectly labeled "10,000 Mark".  The official name for West German currency was "Deutsche Mark", only  East Germany used the single word "Mark". However, bonds did not  exist in the communist East and even if they would have, they had  not been worth a single cent in the capitalist West. Second, in  Germany the number "10,000" means "ten point zero zero zero", not  ten thousand like in the USA. Even if its just about ten Mark,  nobody would add three zeros for a currency with only 100 fractions.
