Sell an ounce gold coin on EBay and they charge 10% commission and PayPal takes their share. So you pay $1600 for a Gold Buffalo $50 piece, then you figure it's worth at least $1600 after 10 years but you walk away with 1350-1400. It is better to sell it for the spot price of gold to APMEX IN OKC which is around $1500 and no EBay or PayPal robbery. You lose money either way but with APMEX you come out ahead-sort of.
