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.

Unfortunately, the characteristics attesting the genuineness of used first issues are very difficult since the used ones are always cancelled by a ”grated cancellation”. Given their value, expertization is well recommended. The certified one above is not a great sample but was still valued at $3,000.

Characteristics of the original

  1. Note the shape of the serifs on the “S” and the position of the oval relative to the frame line above.
  2. The shading from the previous printing pass is visible in the letters “P & S”.
  3. There is a bar above the “H”
  4. A very thin slanting crossbar in the “H”. There are also 8 background lines between the crossbar and the frame line.
  5. The top of the “G” is very faint.
  6. The right “1” thickens near the base.
  7. The “I” is very isolated from the adjoining letters.
  8. The “H & I” are joined at the top.
  9. The crossbar of the “H” has a slight tilt.
  10. There is no frame line around the ovals.
  11. The “C” is very isolated from the adjoining letters.

With the help of the original printing plate, but without the background of the eagle, a reprint of a private character was produced by Albin Rosenkranz.
The reprint may be recognized immediately, however, by the following:

1. The silk thread in the paper is missing.
2 . Behind the eagle no background is to be found.
3 . The paper differs from the original in many ways.
4.  No shading is visible behind the letters
5. The serifs on the “1’s” are longer
On the right is a bogus non existing forgery from Rosenkranz.

Forgeries are very few.
The book “Weeds” notes 2 forgeries
These forgeries were made by adding a thin sheet of paper behind the stamp with a blue silk thread between them. Soaking separates them.

The serifs on the top left “S” are too small.
The crossbar of the top right “H” is too thick & straight.
The “H & I” are not joined at the top. There is no shading in the letters and around the eagle from the first pass.

The  top “S & H” are too low.
The background is made up of very thin lines.
The central embossing is indistinct.
The oval circles are not well defined.
The outside border is thick.

Fournier forgeries
No silk thread and no shading in the letters and around the eagle from the first pass.

Forgeries probably from the same forger found on eBay
There is a indistinct thread
The ovals are misshapen.
The fake cancels are incomplete.
The central embossing is barely visible.
No shading in the letters and around the eagle from the first pass.

Another forgery with no thread.
Straight crossbar in the top “H”
Embossing barely visible.
Note however that shading around the eagle an in the letters was put in.

Private reprint of 1987

1864 Inscription “HERZOGTH. SCHLESWIG”.
Rouletted 11. Typographed.

1864/65 Issues

Mi 5 Type I & Mi 6 above
11/4 Schilling Type I, wavy lines close together, small letters in the frame.
In this value there is a period after each of the letters “H.R.Z.G.L .,” a dot over both of the “I’s” in “SCHILLING,” and a period behind the letters ” F.R.M.”
In the center of the background a very light colored “P” may be distinguished.
11/4 Schilling Type II, wide wavy lines, thin letters in the frame .
In this value the characteristics are the same as before. But the background, consisting of wavy lines, has the latter set further apart.
11/4 Schilling Mi 6 (right above), wide wavy lines, thick letters in the frame.
There are no periods behind the letters “H R Z G L” and “F R M” and the dots are missing over the two “I’s” in “SCHILLING.” The letters of the inscription are considerably thicker than in the stamp of the previous issue.
‘SRM’ means ‘Skilling Rigs Mint’

This appears to be the Mi. 5 Type II
The letters appear thicker than the Type I and the wavy lines are slightly further apart.
Note that the 4 is noticeably wider.
The letters in the center are shorter

Mi 5 showing dots over the I’s

There should be an underprint on these stamps leaving a white ‘P’ in the center of the stamp.
