I have the below stamps in my collection and have figured out that they are Polish. However, there does not seem to be any denomination on them that I can see? Does anybody know what kind of Polish stamps they are and what their denomination is? Thank you in advance.
The first stamp, blue 1954 SG O871 (up to 60 grms), is for ordinary post and the second two, red 1954 SG O872 (1z.55) & 1945 SG O806 (1z.55), are for registered post.
There are two version of the last stamp, with or without control numbers at the bottom right.
Keep safe and roll on the vaccine.
