There is probably more 24K gold out there thank you think, especially in areas that are politically unstable.
Gold that pure is bullion, with the same purity as the Canadian Maple leaf gold coin or may be even purer.
Wearing a bracelet, necklace, or ring of this purity is less likely to raise an alarm, if you are fleeing than carrying gold coins in your pocket.
Especially, if you have to go thru airports. The links of the chain can easily be broken off and exchanged for what you need. just like the silver spanish 8 reales (IIRC) were broken into bits.
