I have returned 4 autos since 2009 and the latest (2 weeks ago) a Jaff Decker limited to 199 (jersey with auto) with a smudged auto. In all 4 cases I received back a NEW card with a perfect auto. This never took more than two weeks. The Jaff Decker I just got back, like two others, were serial numbered and that is what I got back no substitutions.
Will always be looking for 2012 or 2013 Panini Cooperstown Signatures for the two sets I'm building-Will trade in your favor--will ship first--Thanks
