If it came back a PSA 10, it would be worth about $1,620: $1,305 more than a raw Near Mint copy after about $45.00 of grading and shipping costs. A PSA 9 would be worth about $485.86, $170.94 more after costs. Most cards do not get a 10, so it may be worth grading only if your copy looks perfect. Graded values marked “Bull Run estimate” are the Near Mint price times a typical grade multiplier, not a real graded market price.
