Mostly BIN/OBO. I am selling a mix of vintage autos with PSA/DNA or JSA authentication (i.e. Vince Lombardi, 1957 Braves WS Auto Program, etc.), modern autos (i.e. Favre, Reggie White, etc.), and modern high grade low pop PSA cards (i.e. PSA 10 michael jordan autos, magic johnson autos, raw kobe, durant, jeter, others). Check out the inventory at the ebay link below.
