So far in my ebay searches, I believe there are the following:
Base Set Parallels: Cracked Ice x/30 and Green Prizm x/25
Fire on Ice: Prizm x/35 (which as far as I can see from the pics looks very much like the pack-inserted version but the pack-inserted is x/25) and also a Green Prizm x/25.
If anyone can confirm if that's it or if I've got anything mixed up, would be grateful for info.
Here's hoping that one day Panini will clearly stamp all their expo cards, and is it just me or is it confusing that there is a Prizm main set with "base" cards as well as "Prizm" inserts, plus "Prizm" inserts in the Select set that came out shortly after... trying to keep my watch list organized on the 'bay is very time consuming (yeah yeah, I know, #FirstWorldProblems).
