Everything depends on how you are selling.... when buying a collection, I expect the holsters are included. helps make it worth my while in case I screwed up on one of the guns
other wise, holsters, if not messed with (cut down on the inside, etc) are worth $100 for crappy, to $350+ for nice ones. Several of these look very nice. One had an issue, I don't remember which one, after I looked at the photos. I looked, bottom right is a Portuguese, these are worth less, but it has the cleaning rod, so around $200 all together, the others, I would need to see an inside to ensure they are not cut down (I have had several, VERY nice ones, but their value was in looks and not collectablity)
Same with the lugers, 2 looked much nicer than the other two - not bad, but condition is everything in collecting (after originality).
