Do stamps in your country expire? 🤔

[Mr-Krabs]

In China, the face value on the stamps is always valid,you can use it all around China.The only different is that the post office may change the tariff .For example:
The domestic letter tariff of less than 20 grams was mainly adjusted four times. The first time was in 1990, the tariff was adjusted from 0.04 yuan in the port and 0.08 yuan in the other port to 0.10 yuan in the port and 0.20 yuan in the other port. The second time was in 1996, the tariff was adjusted from 0.10 yuan in this port and 0.20 yuan in other ports to 0.50 yuan regardless of this port. The third time was in 1999, the tariff was adjusted from 0.50 yuan to 0.60 yuan in the local port and 0.80 yuan in the foreign port. The fourth time was in 2006, the tariff adjustment from the port 0.60 yuan, 0.80 yuan outside the port adjusted to the port 0.80 yuan, 1.20 yuan outside the port.

So,what you should do is just scrape together the expenses.

In France, stamps are valid forever.

For the ones in Francs, you “just” have to convert in Euros to have their value. But with inflation, the very old ones have a value less than 0,01 cts so it’s only decorative at this point

There is ONE exception. The stamps with the face of Pétain on it are not valid anymore and it is even forbidden to put them on an enveloppe ! (as it should be)
