This is a very special Collings D1A originally sold by Acoustic Music Works to Bill Collings Attorney. Features a rare custom Tony Rice style pick guard if you catch my drift. There is some light fretwear as pictured however it does not seem to impact playability or buzz With low action. See below for some more details from AMW.

Of the classic series D1A guitars, clearly the most robust were the labor-intensive micro-thin finish *varnish* guitars offered by Collings for over a decade.  This guitar dates to 2006 (ser #12730) and is one of the best examples we’ve ever heard, and it sports what is clearly the nicest TR-style pickguard this country boy has ever seen. Trust me ;-) 
This D1A is one of our AMW customs, with the added amenities of Style 3 backstrip, tortoise-bound fretboard and headstock with crosscut ivoroid purfling, and the 1 and 23/32” nut width (2 and 3/16” saddle spacing.)  This guitar is a hoss, it is a take-no-prisoners workhorse, and it is a thing of resplendent beauty.  It will sell quickly, and it will serve as a trophy for a life well lived for the person who acquires it.  It’s that simple.
