This is for long tern wealth preservation. Premium for smaller coins is getting out of control and I really always wanted a 100 oz bar!
Question. Why are you looking to buy 50 or 100 oz bars? I'm talking wieght wise.
I honestly don't see how a shiny metal bar will do you any good in SHTF, I'd rather take the money spent and get food/supplies. To each his own.
As the post was made in a Survival forum, I thought the same thing. Buying gold, silver, etc., is a complete waste if it is in preparation for a governmental/societal collapse. It will be worthless.
