MattSince apparently there are no listing in VCP, I have found at least 2 auctions for D350-3:

and a Mastro auction that ended on 6/20/2007 where a lot titled: "1921 D350-3 Standard Biscuit Uncatalogued Trio (3) Including Baker" went for $161.00
As I mentioned above, those prices are at or below the prices of the E121 "sister set."
