I consider physical silver the best insurance of all.
I like the generic silver 1 oz. with no premium other the manufacturing cost. I prefer Australian or Canadian silver coin or mini-mintage from GSM.
Also, junk silver, old US dollar or half-dollar coins from 1964 or earlier. The over 100-year old silver coins are great just to look at. They are great to pass down to my grandkids as well.
Nice. I am all aobut the US junk coins as well. They strike a happy medium between premium and value in my opinion.
Plus I am a history buff. I find the fact that NO ONE I talk to has any clue about the monumental shift in our US money post 1964...
