No, that one is just a MCS. The wolverine (?) is pictured here but it didn't come with this lot. It did come from a collector or someone with marble knowledge from what I can tell, but I combined it in with these that all came in the mail the same day.
Even if it's not a wolverine, the big find of the year for me is probably going to be the green fizz. The more messages I get about it, the more rare I realize it is. There may only be a double handful of them or less known to exist.
