Is it valuable to stick stamps?

There are two types of stamped stamps;

Letters-selling tickets-are stamps stamped and sold by mail and have been used in circulation.

Stamp cancellation-collect stamps that are not used in circulation.

Generally speaking, the value of letter sales tickets is not as high as that of stamped sales tickets, because the appearance of stamps is not as good as that of stamped sales tickets. Stamp covers are usually sold at a discount. This kind of stamp is rare in China now. In the actual mailing process, stamps are letter sales tickets. To put it simply, if it was in the recent 10 year, it would be worthless, much lower than its own value, and basically has no collection value. Except for individual letter sales tickets stamped with commemorative postmarks (usually such tickets should not be torn off from envelopes, and stamps will be more valuable once sealed). During the Ming and Qing dynasties, before and after liberation, the usual tickets sold on credit had collection value, but their value would be lower than that of new tickets. Some stamps have fewer credit sales tickets than new ones, so they will be higher than the value of new ones. But only a few. No one will accept the letter sales tickets taken from the letters in circulation now, if they are to be sold in the postal market, but it is quite painful for stamp collectors to throw them away, even if they are residual tickets. Anyway, I usually stay, and the value is for myself. Just make sure whether I am a stamp collector or a postman before collecting stamps.
