Again, the 19-5 DSS/CSP does not appear to deviate much if at all from what comparable condition, non-P&R 19 snubbies sell for. One would think it would, but it doesn't; I pay a little extra attention because I like the DSS version, but as you can see from this thread alone, the finish itself throws a lot of people off (and sometimes gets greats deals), and I think that's part of the reason why only aficionados of this particular version of the otherwise ubiquitous 19 snubby know or care much.
Yours looks from the pictures to be in very good cosmetic shape; presumably it's mechanically sound, too. You don't mention whether original box, tools and docs are included, which does affect final price.
Your best bet for a sense of what you might get in trade value or private sale is to look at what regular 19 snubbies are selling for. Fellow member 5Wire is the in-house tracker of this; linked is, I believe, his most recent post tracking sales.

Again, if gun alone in excellent condition, I think you're apt to get in the $700 range, with some swing in either direction based on changes in the weather.
