I was taught that. I have heard it. Read it. Googled it. I still don’t believe it. A lot less than the Washington monument to put into perspective. Walk into countless pawn shops, jewelry stores, ect. and I can’t fathom that there is only that much in circulation.
Yeah, the goldbug nuts can’t believe it either, or just deny that it’s important. That’s one of the problems with math, it gives the real answer and/or accurate estimates.
