Herd of buffaloes

I'm a FNG here...just joined although I've been at it since Pres. Johnson. I joined NGC mainly because of the multi-coin holder.

I want to do a 3-coin set called the Buffalo Herd. I have a 1913-P MS-65(nice even nickel color and luster), and I just bought the 2006-W Unc. bullion 24 kt $50 (boy, that's a mouth full). All I need to find is the Unc 2001 Buff commemorative.
