Issue I (Eagle Stamps)
IntroductionStart here if your stamp has an eagle on it. These are mostly 2 gr. red and 4 gr. blue, although proofs exist in various shades of green, olive, brown, orange and gray, and are illustrated below. If your stamp doesn't have an eagle, go back to the identifier home page
The emphasis in the entire identifier is to use measurable points of identification, and eliminate as much as possible of subjective judgment for identifying Przedbórz stamps.
This is especially important in identifying Eagle stamps.

Step-by-step guide to Eagle stamps
Proofs (in various colors - the bottom colors here are not very accurate.)
First, look at the wing edge nearest the E in the left Przedbórz. Is there a dot on the inside edge of the wing? Yes - Go to Wing Dots, below.
No. It is a type 1, 2, 3, or 5 forgery. Go to F1-3, 5, below.
Is the dot attached to the U representing
a feather, and quite separated from the wing edge?
|Forgery 4 dot|
Is the dot attached (or almost attached) to the wing edge, and quite separated from the nearest U?
Yes - It’s a genuine stamp. Go to Genuine Issue I, below.
No - Is the dot connected to both the edge of the wing and the U (symbolizing a feather)?
Yes - it's some sort of rare freak. See an example.
If it's not any of these, go back and start over, because you've exhausted all the logical possibilities. Something’s wrong.
No - Go back and start over, because so far as we know now, these are the only two kinds of dots at or near the left wing edge. Something’s wrong.

Genuine Issue I
There are eight major types of the genuine 2 Grosze and 4 Grosze stamps. If you want to know which type you have, continue here. First, write down the numbers 1-8, because you may have to exclude the easy-to-identify types, and narrow in on some of the harder ones. You’ll see examples on the appropriate page where the numbers are in strikeout font as the corresponding stamp type is eliminated.
Is the stamp denomination 4 grosze?
Yes - Go to 4 Grosze.
No - It’s 2 Grosze.
Look at the bottom Grosze. Is there a “Fat-G”, or “Short-top Z”? (The Fat G is about 1.6-1.65 mm wide vs. 1.35-1.4 mm in genuine stamps. In the Short-top Z, the top bar of lower Z is about 1.2 mm long vs. 1.4-1.45 mm on genuine stamps. The top bar starts about 0.2 mm to the right of where the bottom bar starts.)
Yes – it’s a F1 forgery.
No – Continue
Is there a “Tight-Mouth G”? (The opening in the mouth of the lower G is about 0.1 mm, vs. 0.2 mm on genuine stamps.)
Yes – it’s a F3 forgery.
No – Continue
Is there a “Slope-Top Z”? I.e., does the top of the Z slope up slightly when you look from right to left?
Yes – It’s a F2 forgery.
No – Continue
Is there a "Wide Open G" and a “Half-top Z”? I.e.,
Yes – It’s a F5 forgery.
No – We have a potential problem: Either a mistake has been made in looking at the various stamp characteristics, or you have a forgery which not been previously identified. First, try starting over again, to see if you missed something.
In addition to having a wrong dot on the left wing, F4 forgeries are characterized as having a Wide-mouth G (opening in mouth of lower G about 0.5 mm, vs. 0.2 mm on genuine stamps) and a Narrow Z (bottom bar of lower Z about 1.3 mm long vs. 1.4-1.45 on genuine stamps. ). There is a slight hook at the left edge of the top bar of the lower Z. Second-from left lower U is usually broken on the left side, producing a dot.
