Inflating your collection : 1 German Empire (Weimar Republic) d

By November 1922 (still within the 3rd emission of that year), two 50,000 RM notes are issued.
One comes without underground printing, the other with underprinting.

Pick 79 / 80 without and with underprinting

detail, without and with underprinting

In December of 1922, a fourth set of notes is ready to be issued.
A new 5000 RM note (smaller) is emitted - according to Pick, with 5 different watermarks 

5000 RM - Pick 80

First note (80a) is with watermark E.

Lots of notes have the letters in the watermark hidden behind the heavy printing on the note.

6-pointed star with letter D in the watermark

Other watermarks are G (80b), I (80c), F (80d) and J (80e).

watermarks F, G, I and J

Next to the watermarks, some other differences my attention :
Some notes have one letter behind the serial number, some have two letters.
There is also a difference in lettertype of the 5 and the 7 if you take a closer look.

Note E...O and M...PG have different "5's"
Note S...WO and M...PG have similar "5's", but different "7's"

The "6's" in note H...U and M...PG are slightly different too, and in my opinion, are also the "2's" different:

Finally, another 1000 RM was planned for December 1922, but wasn't issued.
The note was used with an overprint with a higher denomination later.
