My LCS has a very simple method for pricing bullion, junk silver and generic pre 1933 gold. Every morning he is sent his refiner report. This refiner report shows what the refiner will buy for what price and what the refiner advises the LCS to price items at. For example, todays price for ASE was $19 for sale and LCS will buy at 14.50 For Numismatics, he uses greysheets. What does your shops pricing system look like?
