I LOVE these, Rowedean!. I'd go hiking/photo shooting with you anytime. You did a great job of capturing several outdoor scenes. I'm easy - if there is water in the frame, I'm hooked.
It was a play on words. Everyone I know calls them buffalo nickles.......
To each his own, except when they want to change me. (They quit minting them in 1938. https://en.wikipedia.org/wiki/Buffalo_nickel, even Wikipedia re-directs from "bison nickle".)
I actually rode a Buffalo once in the Philippines - a Water Buffalo with long, sweeping horns.
