So I go to the website for one of my favorite banknote dealers - one of the larger Asian dealers for PMG notes... and I see... this.
This feels like quite a change from early to mid-2019, when Banknote World was dumping Zimbabwean inventory - PMG graded notes included - in 50% off and 60% off fire sales, seemingly desperate to be rid of it all. And that was after they'd already reduced their base prices on a number of graded Zimbabwe notes!
I feel like, in the last year, there has just been a massive swing in the interest in these.
I think the rising inflation and people using words like "hyperinflation" in American media are getting people interested in these again.
The Zimbabwean notes have a big advantage over the old Hungarian and Weimar Germany notes because they are 1) Plentiful and cheap in high grades and 2) They're in English, which is just going to make them inherently more approachable than most other hyperinflation notes, like Yugoslavian notes or even Venezuelan notes.
