It’s a fair question. After all, King Charles III’s face is now on new stamps. But here’s the cool part: the Royal Mail doesn’t make you swap out your old stamps like an unwanted gift.
They treat them like national treasures. As long as the stamp is intact and hasn’t been used, it’s as good as cash. It’s like finding an old fiver in a jacket—you don’t question it, you just spend it.
Compare it to a vinyl record. You wouldn’t throw away a Beatles album just because a new artist released a song, right? The Queen’s head stamps are the vinyl of postage: timeless, slightly vintage, and totally functional.
