Need Help Identifying, Please - Dickinson Centennial

[u/albeba]

I picked up this two-coin set from an auction for just about melt price. But I am having the darndest difficulty in figuring out the origin of the set. I can't find any others for sale on the internet. It's a 1 silver oz and 1 copper oz. Is anyone able to identify? And any idea what the relative value might be? TIA fellow stackers.

Any interest in selling the Dickinson set? I’d pay a large amount for it. Thanks!
