most of the stamps aren't shown in their original size. or the size don't fit with the other stamp at the left or the right side. the first shown German stamps can be rare, if they are originals. The Germania stamps are very common, also the Hindenburg stamp, which don't fit to the four stamps on the right side, Also very common. all four are mass-produced.
Thank you very much for the comment, and knowing that they are produced in series, I didn't check this so I'll see if I can find some with few productions, let's comment that these have little and not many, that's cool, please.
No Brasil tem o mercado livre,também o eBay,você pode pesquisar os valores dos seus selos e colocar para vender,tem leilão e compra direta,boa sorte,obrigado por entrar no canal.
Now that there will be no more stamps, they will become scarce and prices will tend to increase much more. How good it is to have stamps that many people want.grazie.
