A small sampling shows some cards selling for 50% or more of the box price.
For example 3 different Evan Longoria relic autographs sold today for between $55-$61. Not a bad pull.
A pair of Joba Chamberlain relic autos sold for between $40 and $46.
The real question is once the weekend is over and the initial rush to buy the newest release is over, will these cards maintain these prices? Time will tell.
Personally, I think the design is a bit of a hatchet job with the ticket stub relics in particular. Anything that interfere with the player image means, USE A DIFFERENT IMAGE OR DESIGN.
The other thing that people are weighing in on is the randomness of the tickets used. Collectors know a themed design is crucial to a successful product, and the game date needs to correspond with the card back and ideally be a game of particular significance to the player or team.
I will reserve final judgement for a little bit still.
