I got a couple redemptions replaced by Panini a couple weeks ago, and was a bit puzzled by the contents of what I got. They did just fine in what they replaced the redemptions with, but you'll see what I mean by "puzzled:"
Redeemed: 2013 Limited Material Phenoms Montee Ball Patch/auto /299
Replaced With: 2013 Elite New Breed Stedman Bailey Patch/auto 16/49
Redeemed: 2012 Limited Material Phenoms Bernard Pierce Patch/auto /299
Replaced With: 2013 Select Montee Ball jersey/auto 499/499
Did you see that there? One of the replacements was for a Montee Ball card, but one of the cards sent to me was a Montee Ball card. Now, the first thought is, well, the Select card was a sticker, which they likely got signed at the NFL Rookie Showcase en masse, while the Limited card would be an on-card sig, and the card wasn't actually produced at the time. That wouldn't be the case though, as the Limited cards use sticker autos, too. The only other reason would be the release date. Maybe by the time they used all the stickers for an earlier product, they ran out before they could use them all on a later-released product. That doesn't appear to be the case either, as Limited was released on Nov. 13, 2013 and Select was released on Dec. 18, 2013.
Don't get me wrong. I though Panini did a good enough job replacing these cards, I just thought it was funny that I essentially asked for a replacement of a particular player, and received another card of that same player.
