I have been selling to Mark for approximately 2 years. If you have any gold, silver, platinum in coins, jewelry, flatware etc.--that you are in the market to sell, sell it to Mark but be quick at the prices he pays he won't be in business forever. Or prices have gone up so much in the last 12 months he will be retiring soon. Don't send your valuables in mailing bags, envelopes or boxes to strangers. Meet Mark in person and get paid 30 to 40% more than the baggers in the newspaper and television ads. Remember those ads are paid for with your money. Stupid move!
