Wasn't the .1 Cas Silver the rarest produced, maybe version 1? I'm trying to remember if anyone else does.
Edit: Nevermind, it was the .5 Cas I was thinking of.
Oh, hey msin. It's been a long time. I know you a little bit since the old Nxt days, I had a different username back then. Maybe i'll dm you to joke about the past, I think we might have a few things in common.
It is still quite rare with the highest premium for its denomination? but yeah, I think the .5 is rarer.
