Not sure if this is applicable. Is there any value for 99.99% Au Gold? Usually used for gold coating purposes.
If yes, who buys them..gold merchants, banks, etc?

I mean in a shape of a thin foil in Ø60mm x 0.1mm.

From my understanding, gold is used as a tool of some sort to preserve the value of our money against inflation (pardon me if i used the wrong term), unless of course one is an active trader in buying/selling.

If the price of gold is stagnant for a short period of time, let's say for a period of 1 year, would it be a better idea to put the money in conventional tool like FD instead?

Thanks
