Ryan, let's add a Baltimore News Ruth to your list, shall we?
For me, more general-
-Add another cool T206 printing error
-Add another tough T206 rare back
-Possibly acquire another '52 Topps Mantle(*)
(*)After stupidly selling my PSA 3.5 way too soon...although I did use the funds to acquire a Game Used Jeter Rookie Bat, a final season Game Worn Jeter Full Uniform, and a PSA 9 '93 SP Jeter Rookie...so I can't complain.
