I do not believe gold or silver will ever be monetary metals again.

Silver's uses for ultra-super-high tech equipment will be so important that some govern-cements will make it a national security level commodity. None will be left for making coins out of.

Gold's uses are piss poor, and we have multiples of the "stated global gold quantity" stored away in vaults. Rots-children have enough gold to suppress the gold price to $20 an ounce, and keep it there for a long time. (banks barred from purchasing) Further gold has fallen so far out of use as a monetary metal that only really old people will remember as a means of exchange.

Plus cryptos are just that much better than gold as money, as a means of exchange.

However, this does not mean there won't be people panning for gold all over America when food shortages / price increases hit.
