I'm going to put a little less on its value @ $900 - $950
because
1) R9 without sights just dont bring as much money and are harder to sell
2) Black frame two tone guns dont bring nearly as much as a gray or silver frame carbon fiber gun (unless its a stealth with CF grips witch are seldom found for sale)
3) The NO box, 2nd mag, paperwork thing
Although I have bought quite a few Rohrbaugh pistols and watch the auction sites like a halk for them these are only my opinions and I am wrong quite often.
