Inverted watermark

Many stamps with inverted watermark are extremely rare. After 10 years of intensive search I have only succeeded in finding 2/3 of them. How the catalogue prices are determined for most stamps is a riddle for me.

I have marked the stamps with a code for my experience with the stamp.

A = The most common stamps. Those stamps you see regularly and the catalogue price can be used.

B = Rare stamps. Can be found, but don't discuss the price.

C = Stamps I have newer seen or only 1-2 times.

Known means known/seen by me. "*" means known unused and "o" means known used.

Mirrored watermark

All stamps with sheetwatermark cross is believed to be found, not with inverted, but with mirrored watermark. No studies that I know of has been made to tell anything about how common it is.

Most of the Danish stamps from the same time are common with mirrored watermark, but there are exemptions, even stamps that are rare with normal watermark cross.

As a new collecting area, mirrored watermarks are not recognized by most collectors, and at the moment they Known no extra value.

Normal watermark cross	Mirrored watermark cross

Codes for how often they are found. Some stamps are based on a small number, so take it only as a guideline and not the holy truth.

• = = Both types are equally often found.
• > = Most commonly found
• < = Least commonly found
• All = All stamps found (so far)
• - = None found (so far)
