Millions and millions all in various rooms......in one corner of one room was $5 million in $1 bills on pallets, in other rooms was sheet after sheet being printed, cut, inspected, wrapped, etc. Of course, this was seen on a tour of the Treasury Building in Wash, DC., many , many years ago. (Back in the late '60's). The stack of $1 bills was jsut to show how many dollars it took to make that much money.......damn, was a big, high stack on numerous pallets.
I'm sure there was more than tens of millions in the building we saw, probably hundreds of millions........and all of it 20 feet below us as we walked along a raised corridor fronted with bulletproof glass and armed guards stationed here and there. Interestingly, no guards on the printing floor.....at least that could be seen. Lots of cameras, though.
