Depends on where and who you buy your gold coins from. There are gold coins and then there are… “GOLD coins”. All are not created equal and some are worth more than the quantity of gold in the coinage.
Most gold coins are nothing more than bullion, an easy way to contain and identify the value of the metal, and they don’t sell for much more than the value of the melted gold. They can be viewed no differently than gold bars. Are gold bars a scam?
