Bakelite magazines, like most collectable things, do have a sort of ranking system for determining overall value. Unissued / New Old Stock will tend to be the most sought after generally for collection purposes, especially with crisp stamps (OTK, among others). NOS will generally be in better condition than most, but AG-S4 (what we incorrectly call bakelite) is susceptible to wear marks so even unissued magazines can show some wear on the bodies where they'd rub against each other in storage. Once you start seeing paint removed from the rear locking lug and scrapes alongside the top section of the magazine, you move from Unissued / NOS to used in its varying conditions. Tula (identified by the star) is considered a little rarer and as such a little more collectible than Izhmash (triangle with the arrow inside), unless the Izhmash is "Cyrillic" (identified by what looks like a "UT" followed by a number); the Cyrillic Izzy's are something like a 5th gen bakelite magazine and fewest in number overall compared to previous generations.
Your pictured mag, for example, looks like it has no paint removed from the rear lug but it does have a scrape along the left side of the top section; it was likely inserted once or twice and then never again. 4th gen, "Cyrillic Tula" (number then what looks like a "B"), should have metal reinforced feed lips and a smooth back (no ridge along the spine). Not a bad way to get a bakelite collector mag without going full retard like some of us are guilty of. Sharp lookin' magazine.
