Nope, made them from clad quarters. I wish I had known they had those. I would have brought a few junk silvers along. First time I had seen this type also.
It surprised me the Yosemite store did not have the comm.'s coins there also. I did get another nail on aluminum medallion for my walking stick though. So far for that parks I've visited include Yosemite, Grand Canyon North rim, Grand Canyon bright angel trail, Zion, and Arches. I need to order a couple more for other places I missed getting while I was there.
