I picked up 5, 6-card packs of 2013 Panini Cooperstown the other day, since I had liked last year's set. Here's what I said last year. The cards were a bit more expensive this year ($0.72/card vs $0.62/card) and I don't like them as much. They are a bit dark for my taste. I do like the new feature in the back. Last's years cards featured a short player bio, this year's have a line score from a game in which the player made a significant contribution. Pretty much all the inserts are different and there are a lot more parallel cards this year. Not necessarily a good thing. There are relic and auto cards as well which I didn't expect to find in loose packs, and I didn't.
Here's card #2
I always like getting old Phillies in these kinds of sets.
Every pack has one of these in it. Colgin's Chips.
A new insert this year is "Historic Tickets".
Panini Cooperstown Induction is the one insert returning from last year.
