Braves are a big market team which helps a lot on when selling on ebay. It all depends on what you have, really. Hank Aaron/Chipper Jones stuff will always fetch a nice price at auction.
Baseball: Trout, Altuve, Orioles(Schoop, Walker, Mussina, Gausman) What I collect: base, inserts, refractors, low cost autos. No relics. 90's-Current. Trying my hand at very low-end O's prospecting.
