what's the cost to sell a gold coin? I know the dealer spread is disgusting
Where I am I can do that at any bank. That's pretty much the only reason to own gold for me. Spreads are around 10%, 6 for full ounces I think.
i have an online broker who trades gold with a spread of 1.5 usd

buying physical gold ounces at the corner store is for begginers
Buying precious metal where you can't physically touch it means you do not really own it. It's like the US government has never taken gold away from the population during unstable economic conditions...
