Probably not many opportunities to catch full sets.
Is there any reference site to see which coldkey-card were released exactly? I have a vague knowledge but missed some and an overview of them would be nice to have.
This is something I've actually been working on (and off lol) for some time... I started with Krogs's initial thread, but the full list is now longer and will take some more time, but when done will be on the new/updated coldkey website (That is the plan, anyhow).
Nice, looking forward to it. There are way more coldkeys out there than I was aware of.

My goodness, that thread (I haven't visited in a while) is always a stunner. And indeed great reference to any coldkeys - however, for whatever reason, many of the historic CC series image's didn't load. It felt like a browser problem, but happend in Firefox as well as Chrome.
