Yes, the Sovereign Native America Nations see value & wealth in Silver Dollars, too.
I am always happy to find Silver (0.999) Dollars, mixed in with Silver One Troy Ounce Generic Rounds, at the Local Coin Shop. And, like many other Governments, they are backed up, with one fiat dollar. Go figure. Anyway, I really like them.
I was happy to trade $29 (USD) paper fiat, The premium was about $5, each. Apparently, this Native American Mint Coin, is one of, at least, 39 different Silver Dollars. Looks like they have produced, about six per year, since around 2015 or so. I have not be able to find much information about them. Thanks for looking, and, please add any information about them, if you are familiar with them. Check out #silvergoldstackers, to see other interesting, Stackers' Treasures. Happy Thanksgiving!
