The first pack is 2013 topps platinum. There are 5 cards in this pack and I feel that these are higher quality cards than your standard packs, not top shelf or anything but I'm sure this will go fast once it's up for grabs.
The second sealed football pack is one I won on a listia auction. It's a pack of 2010 panini crown royal football cards. These have a high chance of having relic and auto cards in them and the seller says this is a guaranteed relic card so who knows what might be in it. There are 5 cards in this sealed pack as well.
