As precious metal prices make coins too valuable to be used in regular trade, the majority of current coinage are composed of non-reactive base metal alloys. However, the various precious metals that are used to make modern investment coins and bullion include gold, silver, platinum, palladium, and rhodium.
As they have been for millennia, precious metals appear to have a long future ahead of them as a store of value. Because of their beauty, scarcity, and industrial significance, they have always been a variable in human history, whether they are retained in their pure state or turned into coins.
I don't know about aluminum. I asked bing, and the response was:
Aluminium is not a precious metal. Precious metals are metals that have high commodity price levels, such as iridium, rhenium, ruthenium, rhodium, palladium, osmium, platinum, silver, and gold. Aluminium is the third most abundant element and most abundant metal in the Earth's crust, but it was very difficult and costly to extract the metal from its ores until the 1880s. Since then, aluminium has become a common metal with a huge demand in the market.
Nice to see you using AI ! Was a "precious metal" aong time ago before they figured out how to make it cheaper !BBH
