Gun Broker has an advanced search function that will allow you to view recent closed auctions, so you can see what sales have brought in. Currently, there are both a desert camo 91 and 93 on a consignment listing at the same dealer on GB each for $3500, which I would say is too high. There is also a woodland 91 listed as very good condition for $2400 that also hasn't seen any action. I haven't seen any for a while on this site, but I purchased a HK93 camo (ii date code) last year for $2400. I think that the release of the MR556 and MR762 have really hurt the prices of HK91/93s, with the thought being why would I pay more for a 91/93, when I could just get an MR556/762. I'd recommend looking at what new to like new 91/93s have been closing at and adjust your pricing accordinly.
