You really get a lot of of cards out these cases. Wow! I mean that in a good way as it's a really fun break and prices are incredibly reasonable on these right now. I picked up my case last week for $355.
Topps did a great job this year with their core baseball product. The insert sets were all really cool and the Million Card Giveaway was the best hobby promotion ever created. These jumbo cases are loaded with inserts and the really cool bat barrel cards. You also have the chance at the always popular SP veteran base variations that seem to run 3 to 4 per jumbo case. Of course, the black and gold parallel cards are there as well. One last bonus is the Topps Chrome Rookie Box Toppers.
I beat the odds on this case. You're supposed to receive one autograph and two memorabilia cards per box. I ended up with seven autographs, one being a redemption, so you could argue that I got six autographs. I also ended up with seven bat barrel cards which are supposed to fall one per box. The seventh bat barrel replaced one of my All-Star jersey cards, which I only got five of. I also got two silk cards and two black parallels. The case only yielded four of the original back CYMTO cards.
I've read that you can make six base sets out of a jumbo case. I'm assuming that's true as I got six of the #661 Stephen Strasburg rookies. I'm not so sure about completing a master set. I got a lot of doubles in the Turkey Red and CYMTO sets. I'll report back after I've had time to sort all of these cards. I don't know how I'd manage breaking multiple cases of this stuff.
