Parallels include white (1:120 packs), black (#/15), and "First Fifty" (#/50). The minis are the best parallels, though, because there are seven different historical back types to chase:
The previously mentioned box toppers come in three formats. The 5x7 toppers has 12 cards (1:40 packs), and there's a 30-card Darby Chocolate 3-card panel set (1:60 packs) as well. Found 1:24 packs is the Hobby Box Bottom Three-Card Panel; with nine cards in the set there must be three separate panels. It's interesting that they give pack odds instead of box odds here.
I really enjoy Golden Age; Panini makes a strong effort to bring new, oddball subjects to base set, and to add autographs and relics of those subjects whenever possible. I know I want a base set already, and the mini backs are very appealing. I see several cards on the autograph and relic checklists I wouldn't mind having, if prices are reasonable of course.
As for the inserts, I've been trying to build a mini-master set of 2013's cards but they're quite pricey online, which I guess is a good thing since that means they hold their value. Depending on how this year's cards look, I might try to do the same, but I really would like to decrease the number of sets I'm working on.
Now, if only Panini would do a modern version of a set like this, with active players in multiple sports and current celebrities, musicians, and actors. It doesn't need to have a throwback design, something similar to Americana but with more-popular, current subjects.
