This is the first machine the German vending company (TG Gold-Super-Markt) has offered outside of Germany. The vending machine will offer small bars of gold as well as gold coins. The machine will monitor daily gold prices.
Historically when commodities make the headline news and reach out to the retail investor, such as all of the recent television commercials stating how gold has rallied in recent years and why investors should buy gold, this may be a telling sign of at least a short term correction in gold. Keep in mind yesterday gold price made an all time high.
