Do old postage stamps remain valid?

They do! Old British postage stamps issued by the Royal Mail remain valid, as long as they have not been used before. Stamps that already have gone through the postal system cannot be used again, in most cases these used stamps are stamped.

Unused postage stamps remain valid. You can read about this in greater detail on the MoneySavingExpert.com forum.

What about the halfpenny stamps?

Stamps with halfpenny values were available for purchase in the UK until 1985. Unused halfpenny stamps remain valid, as long as you combine them in pairs, so the total adds up to a whole number.
