Well, I can tell you most all of them had incredibly low print runs. These things are MUCH harder to find than AF 15 or such rare keys. It's rare to find these online at all, but when you do, it's hard to find two similar copies. I'd never even heard of the Polish ones until the member who sold these to me explained the history behind them. I'll try to see if I can find the print run in the comic, but it can't have been more than about 1000. Most of those probably went unsold and were destroyed, and the others disappeared or worn out over time. I believe these were printed in the US since they mostly match the paper quality and material.
Rarity depends on the country, though. There are many German and British comics graded on the census, but zero Hungarian, Russian or Polish comics. There are LCS's that stock back issues in Germany and Spain, and probably others. However, I haven't heard of any in Mexico. It also gets hard to find these since lots of smaller countries don't have eBay, but rather smaller auction sites that don't get as many users and aren't as secure. I've been lucky in finding these via the odd eBay listing, and some very nice members on this board who live in countries like Poland, Spain, Belgium and Japan.
The Danish reprints of Spider-Man (which I collected when I was growing up in Denmark) had print runs in the 20-30k range in the 1980s & 1990s - there's no chance whatsoever Marvel would ever give a license to a foreign publisher if said publisher was only going to print 1,000 copies of their flagship title. They were also printed locally - which is the case for pretty much all of Marvel's european reprints.
Thanks for the corrected info (thumbs u
This is still a learning process for me as well. 20-30k I'd love to find some of those in unopened, Mint condition.
