Germany Inflation Stamp - Rare Perforation

I have a lot of german old stamps and between these many inflation from 1923.

I have two questions:

1. Have the perforation on the picture higher value than the ordinary perforation?
2. In stampworld.com catalog I can read "(Penetreted perf.)". Is my stamp (picture) in that category or does it mean perforation like MB, MID og simular?

Isali,
try to be cautious when using "Rare" unless you are sure of your information.

Your perforation is known as "Serrate Roulette" or, if you prefer "Zig zag roulette"

Thanks rod222.

Is this perforation of less or more value than ordinary perforation?

I am not qualified to say, not a German specialist, however it seems not,
looking at Scott, most are 20c issues, the trick with these inflation issues, are to find imperf examples, or genuinely used examples.
Forged postmarks abound.

Thanks rod222.

I have a lot inflation issues still on paper clips or part of envelope and think they should be unwashed for better documentation, but it seems very hard to sell them.

The 50 Million Mark stamps are Michel 321 B P. 2018 Michel catalog value of €8 each for used.

Used stamps of the German inflation era must be expertized and signed by the expertizer to have the value accorded by the Michel Deutschland-Spezial catalog. Knowlegeable collectors understand this. That is why you are having a difficult time selling these stamps. Leaving the used stamps on paper is a good idea.

Forged cancels on these Germany "high inflation" stamps far outnumber the genuine cancels.

I wouldn't bother getting these expertized, if only because the cost of postage there and back will exceed what you could possible hope to sell these for.

In all likelihood, the cancel is genuine -- the used CV is low (€8 per); the face value is within the range one would expect for usage on that date (1 Nov 23); and the cancel is a roller cancel, which would not be what one would expect to see used to create a forged cancel.

Any difficulties in selling these are more attributable to a lack of demand for common hyperinflation issues.

When you say "it's hard to sell them" it all depends on your
price. My experience is that stamps of that era sell for 10%
of Michel value on the best market, the German ebay.de.

Thanks to all, I have learned a lot from these comments. One good thing with german stamps, they have watermark which is quite easy to find - not like norwegian stamps.

As German ebay.de is mentioned, I like to ask if ebay.de work quite simular as (Offsite URL shortening not allowed-2018-09-28)?
