POL perforations 1926-45
Circulating postage stamps have been "Pol" punched by some police authorities since 1926 for internal service reasons.
The perforation was later ordered for the purpose of identification as postage stamps by decree of the Prussian Ministry of the Interior of 8 April 1930 at all major state police authorities in Prussia.
Even non-Prussian police authorities occasionally introduced branding.
There are 50 different types of perforation and 2 sub-types, which can be divided into three groups:
A = three letters of equal height,
B = "O" and "L" different height,
C = "O" and "L" equal.
Since the consumption of POL-perforated stamps has been very different in the individual police authorities, surcharges are justified for the rarer types of perforation, which are indicated for the types.

...commonly referred to by the stamp collecting community as 'perfins'
Examples :
466 POL C22 Gelsenkirchen antwort
This means the envelop holds Michelnr 466 with a POL perforation and this perforation is from Type C22 from Gelsenkirchen as a return answer.
512 and 513 POL B17 Bayreuth
This means the envelop holds Michelnr 512 and 513 with a POL perforation and this perforation is from Type B17 from Bayreuth
512 and 623 POL A2 Frankfurt am Main
This means the envelop holds Michelnr 512 and 623 with a POL perforation and this perforation is from Type A2 from Frankfurt am Main
513 and 580 and D114 POL C22 Gelschenkirchen
This means the envelop holds Michelnr 513 and 580 and D114 with a POL perforation and this perforation is from Type C22 Gelschenkirchen
516 2x POL C11 Magdeburg
This means the envelop holds Michelnr 516 2x with a POL perforation and this perforation is from Type C11 Magdeburg
516 POL B5 Wesermunde
This means the envelop holds Michelnr 516 with a POL perforation and this perforation is from Type B5 Wesermunde
517 POL C10 Duisburg
518 POL B13 Belin-Charlottenburg with ROHRPOST !!!
519 POL C13 Waldenburg
519 POL C27 Frankfurt am Oder
There are many POL perforations not correct (also on letters) to be mentioned :
The surcharge marks (after all, no money was spent on surcharges by the Police) and most of the special values.
Almost all have the same perforation, similar to C27 but without a point behind the L.
Surely there are reply letters which then do not have the stamp of the location of the police authority wear, but these are quite rare.
Some questions with the following examples :
512 and 652 and 654 POL C12 Elbing
Note the 2 stamps with surcharges ???
557 3x and 559 2x POL C1 Recklinghausen
All the stamps with surcharges ???
Block 9 POL B17 Bayreuth
A block with surcharge stamps ???

First an introduction from Wikipedia :
Perforation (philately)
The (company) punching of postage stamps was a security measure against theft of postage stamps by the workforce.
In English usage and partly also in German they are referred to as Perfin, from the English abbreviation "Perforated Initials",
which means something like: punched initials.
A distinction is made between two types: on the one hand, official perforation by authorities and, on the other hand, non-official perforation, e.g. B. by companies.
In both cases, a grid of dots was stamped into the image of the stamp, changing the appearance of the stamp.
The punching did not cancel the stamp, but only indicated it for limited use.
Usually the first letters of the company or symbols were used for this.
Perforations were mainly used as protection against theft.
Companies, agencies and authorities with a larger supply of postage stamps marked their stamps in this way.
This made them unusable for the private use of employees and employees.
Official holes made by the authorities meant that they were used for official purposes, with official stamps sometimes being used instead.
In Germany Bavarian postage stamps between 1912 and 1915 with a stamped "E" to official stamps for the Bavarian railway authorities
repurposed, Australian stamps received the perforation "OS" for "Official Stamp".
This perforation (OS) was later replaced by a corresponding stamp imprint.
The idea of punching postage stamps goes back to the englishman Joseph Sloper, who in 1867
applied for a special punching machine and obtained a license received through the mail.
In 1877 this method was also used in Germany and was there until the 1950s.
Today perfins are nolonger allowed in most postal areas, including Germany.
The stamps with the perforation "POL" for the police authorities were intended for use by the service authorities.
The perforation was made to protect against theft and third-party (private) use, as well as to identify the brands.
The company's perforations should protect the postage and are certainly not to be regarded as official stamps in the traditional sense.
