2008-09 Champs Mini colours?

[56Parkies]

Since I've been back collecting after a 3 year absence, I've been trying to tweak my checklists, and have a question about the 2008-09 Champs Mini cards:

I've seen examples of "different coloured backs" on these; were they done for every card, or just some (rookies, for instance)? I've seen the Osgood card -- #C24 -- listed as having a Blue/Brown/Purple/Red back parallel, but so far I've yet to see a single one turn up on eBay, while the regular black-backed one is there often..

Just trying to confirm whether these exist!

Thanks!

Mini-Card Set o Mini Regular Cards
o Mini Cards, Natural History Collection – inserted 1:3
o Mini Rookie Cards – inserted 1:8
o Mini Cards, Brown Back – inserted 1:24
o Mini Cards, Red Back – inserted 1:144
o Mini Cards, Blue Back – inserted 1:288
o Mini Cards, Purple Back – inserted 1:576
o Champ’s Mini Signatures – inserted 1:12
o Champ’s Mini Threads – inserted 1:24
o Mini Fossils & Artifacts – inserted 1:240
o Mini Hall of Legends, Sports Memorabilia– inserted 1:240
o Champ’s Mini Signatures, Red Back – inserted 1:288
o Champ’s Mini Signatures, Blue Back – inserted 1:576
o Champ’s Mini Signatures, Purple Back – inserted 1:1152

For Gagne, I've only seen the Blue and Red back.

Here's the breakdown on the parallels:
Mini-Card Set o Mini Regular Cards
o Mini Cards, Natural History Collection – inserted 1:3
o Mini Rookie Cards – inserted 1:8
o Mini Cards, Brown Back – inserted 1:24
o Mini Cards, Red Back – inserted 1:144
o Mini Cards, Blue Back – inserted 1:288
o Mini Cards, Purple Back – inserted 1:576
o Champ’s Mini Signatures – inserted 1:12
o Champ’s Mini Threads – inserted 1:24
o Mini Fossils & Artifacts – inserted 1:240
o Mini Hall of Legends, Sports Memorabilia– inserted 1:240
o Champ’s Mini Signatures, Red Back – inserted 1:288
o Champ’s Mini Signatures, Blue Back – inserted 1:576
o Champ’s Mini Signatures, Purple Back – inserted 1:1152

So there were the 4 colour parallels for EVERY card.. You'd think at 1:24 that I'd see a Brown backed Osgood by now.. Clearly I need to message these sellers and ask what colour the backs are!

Thanks for the help!
