This catalogue listing is interesting in that those Mi I-IV stamps have such low numbers of issue but are still relatively cheap. Mi I had only 2200 copies printed but the mint value is only €45. Imagine if those were issue numbers for PR China! The Drunken Concubine souvenir sheet has a catalogue value of $12,500, and 20,000 of those were printed. Supply vs. demand, I guess nobody much is demanding stamps from Western Ukraine ....

Edit: wow, looking further down the list, Mi 58 & 59 were both issued with only 1000 copies, catalogue price is only €18!
