giving them a fair price when they want to sell. They will learn a lesson when gold starts falling. The coin shops universally lower their bids way below spot in a falling market--those that remain open. Others will close down, as they did in 1980 when the top was reached.
In 1980, when I tried to sell my gold and silver at spot (which the dealers paid before the crash started), coin dealer after dealer justified their below spot purchase prices as a way to protect themselves in a falling market. Some dealers lowered their purchase prices 10% or more below spot, overnight. Liquidity in a falling, panicky market goes fast. It will happen again.
