Sopotsopot,
Dzien dobry, panie! If you are asking whether the four stamps you have shown are worth submitting to an expertizing service for a numerical grade in order to enhance resale value, I'd have to say no. The 10-cent eagle and shield is fairly off-center, and none of the others is extraordinarily well-centered, or at least enough to warrant a numerical grade (a possible exception might be the #24, which I'd describe as VF-XF). That said, they are all very attractive stamps and if you were to put them up for sale on
ebay or Hip Stamp you would definitely attract buyers.
