Solid Hits was 1:4 packs, Laying it on the Line 1:5, and Difference Makers is the rarest at 1:20. Other subsets included Clutch Players, True Gamers, Run Producers, and Winning Formula. Griffey appears in none of those, so as far as this blog is concerned they don't exist.
These are kind of inserts, but they can be more accurately described as short-printed subsets. They all contain some form of foil in the field behind the player photo on the numbered side.
I don't see on these cards where they could possibly influence gameplay. Maybe I don't understand the game. If someone has a rules card for this set please e-mail me a scanned image. The mind boggles....
I have some version of every Griffey in this set. Here are the parallels of the base card I am missing:
#30 Orange Parallel
#30 Blue Parallel #/650
#30 Purple Parallel #/50
#30 Red Parallel #/25
In the interest of providing you with high-quality scans of every Griffey in my collection, here's a nice one of each individual card.
Until next time!
