Holy Moly! I had no idea they were even collectible. I have a mostly unmolested Gen 2 G19 (added tritium night sights). Also have one or two U notch mags (somewhere- they should be about like new, I sought and bought some GOOD drop free Glock mags for it). I also have a Gen 2 G17. Also have Gen 4 and Gen 5 19s (didn't like the Gen 3, felt too fat in the hand). And I'm not really even a Glock guy. But they go bang. every. frickin'. time.
