Stamps are divided into large and small editions. What else is there?

There are also parcels, sheetlets, souvenir sheets, four-way couplets and small promissory notes. That's basically it. It is difficult to book large and small editions in philatelic companies, and only old customers can renew them. Generally, we don't develop new customers, so these editions skyrocket as soon as they are released (they can't be bought in philatelic companies, but only in the market, and the price far exceeds the face value).
