> For decades, the stamps were dismissed by the philatelic establishment as tacky novelties and were, correspondingly, as cheap as chips, [...] valued at around £17, the equivalent of £28 at 2015 prices. But following their recent discovery by collectors of rare vinyl, particularly in the US, you will be lucky to pick a set up for less than £300.

I love how one group of collectors goes "tacky novelty!" and another group goes "amazing rare find!" over the same thing. It all makes sense, but it's still weird.
