The stamp on
ebay has no Date in the cancel. then its a low value.
The stamps come from an INFLATION period. every few weeks the value of the Deutsch Mark was lower.
If the rate for a letter was on januari the first, RM 1,00 it could be that at july 1 the rate was RM 100,00!
A few weeks later RM500,00 etc.
Used german stamps shoud be cancelled in the right period, in the example above RM 20,000.
In the Michel spezialized cat are all the right tarifs mentioned.
Many collectors have unused stamps from this period, its the inflation, if you buy "today" 1 stamp of RM 20,000 you have to use for a letter , after a month RM 500,000 ! So the cheap stamps were left over.
Maybe someone has a spezialized Michel Germany cat.?
All info is in there. I cant find my cat. I moved to a new house last januari..
