Congress will hold hearings tomorrow where Congressman Weiner plans to grill Goldline executives over their gold business. Specifically Weiner thinks they are charging too high a markup on the gold coins they sell, charging an average 90% markup on the coins they sell. Unfortunately, a quick check of the Goldline website and a few of their competitors shows that Goldline’s markup is higher than its competitors but nothing along the lines of a 90% difference.
