The price is not below its equilibrium. Very far from it. In fact, the price for Gold Coins will keep on going down consistently with time. The profits countries and enterprises make these days are extremely low, compared to what they were four years ago. These profits will keep on going down for countries, as the size of corporations increase. I won't get into it now, maybe another day, but the point is: it isn't artificially below it's market equilibrium price, but above.
