Adebayo, gold is no more money than a ten-dollar bill or a tulip bulb.
Gold is a commodity that, through the centuries, has been used as a currency because it was distinct and undestroyable.
Money is the strength of a promise to deliver goods or services. It doesn't have an intrinsic value and can be created by work and innovation.
I don't know the exact history of moving from the gold standard. It likely became cumbersome and irrelevant.
Best.
