Just spoke with Tim as it happens. He said that if you have the Item # from your order and it ends in PK, that's a private key coin. Up to you what you want to do with that info of course.

I peeled mine (which was a PK) anyway and transferred the funds away to be on the safe side. I kind of regret it now, because it worked - it was fully funded. But I would have regretted it more if I didn't do it now, and when I tried later it didn't work. So it is what it is - at least I know where I stand now.
