Germany - Schleswig-Holstein 1850

 Specific measures were included in the first stamps to prevent counterfeiting.

The printing office opted to use the American Dickinson Safety Paper for its stamps.
The silk thread was not applied on the paper as some countries did but was actually part of the actual paper making process. Trying to duplicate this was
essentially impossible.
The silk thread was intended only as a protection against counterfeiting mint stamps for mailing.
Furthermore, the print itself was carried out in three rounds. They were first printed with the eagle heads, feathers and the feet.
In the second pass the entire image, including the eagle was printed without the words POST and SCHILLING below.
In the third pass, the embossing of the middle oval took place.
You can clearly see areas that were printed more than once with slightly different colors.
Obviously, a difficult problem for counterfeiters to fully overcome and none did.

Forgeries

The circulation of 1 schilling was 1,300,000, the 2 shillings 700,000 pieces. But it is estimated only 8,000 of the 1 schilling and 4,000 of the 2 shillings, were used making the used ones much more valuable and prone to being fakes.

 Forgeries are very few.
