Swedish stamps issued between 1862 and 1872.
Yvert is 12 and 15; in the local FACIT catalogue it becomes 14B (cheapest version) and 20). Both stamps in pretty good condition, except for a tooth missing on the 20 öre-stamp. When i'll be 135 years old, i'll be missing some teeth too i guess.
The difference between Facit 14A and 14B can be determinated by the right upper corner.
With the 14B it's like this.
The 14A version has an extended line, following the frame. As if the curl downwards starts some milimeters before the horizontal line that proceeds the curl ends.
Type A was only printed 709.200 times, type B 10,5 million times. In the detail you see a 14B.
There's a variation which has a print on both sides. Other errors are various colour spots and lines.
