When do old royal mail stamps expire

Royal Mail stamps, like those from many other postal services, do not technically "expire" in the sense that they become invalid or worthless after a certain period of time. However, there are some important considerations to keep in mind:

  1. Denomination: Royal Mail stamps are valid for postage as long as they are used to pay the correct postage for the weight and size of the item being sent. If the stamp is no longer valid for the current postage rate, it may not be accepted by the postal service.
  2. Design and issue: Royal Mail regularly issues new stamps with updated designs, commemorative themes, and special features. While older stamps may still be valid for postage, they may no longer be in circulation or may be replaced by newer designs.
  3. Collectibility: Stamps can become collectible items, and their value may increase over time due to their rarity, condition, and demand. In this case, the stamp's value is not related to its postage value but rather its collectibility.
  4. Postage rate changes: Royal Mail periodically increases postage rates, which means that older stamps may no longer be sufficient for the current postage rate. In this case, you may need to purchase additional stamps or use a different payment method to cover the increased cost.

To summarize, old Royal Mail stamps do not expire in the classical sense, but their validity and collectibility may be affected by changes in postage rates, design issues, and collectibility.
