“One critical aspect of a earthy marketplace that is mostly ignored is a reward it commands over mark price. Right before a Global Financial Crisis in 2008, a mark Silver cost fell as low as USD 9 per oz., since a cost of a 1 oz. Silver Eagle was around USD 17 on a indiscriminate marketplace and even aloft on a sell market! That’s a cost reward of 188%!
That means that if we had hold 100 oz. of paper Silver, we competence have had to repay that for USD 900 (assuming a marketplace was not halted for trade then), since if we had hold 100 pieces of 1 oz. Silver Eagle coins, we would have gotten during slightest USD 1700 for them if not more.”
