Depends on the buyer, this one is getting collectable. Having the box etc. Does add value. To me and many others. Check the price on the auction sites. Boxes and accessories will bring more money.
The box absolutely adds value.
There's a 6" 617 pre-lock sitting on an auction site right now with no box, no bids for $925.
The 2 statements above are not intentionally related. But, possibly they are.
