Quote:
c$150 difference between mint and used
Shopping around and researching is always called for in buying philatelic and other specialized kind of books. Booksellers without the specialized knowledge will make a big deal about first editions and out-of-print and often add premiums, even if there was only one edition. We'd likely prefer an updated latest edition, if it exists.
Now there are people who collect philatelic books so pristine copies are deserving of top prices, assuming scarcity in that condition. Me, I'd be happy with a serviceable, obviously used copy. Like stamps. And some philatelic books are rare, but so are the buyers for them. Like stamps.
