GOLD.
Gold has intrinsic value and can be used as a store of value so that the whole world accept gold as an investment asset. When someone buys gold, he understands very well that anyone will recognize and accept gold, because what he buys is a metal that has value.
There's no such thing as intrinsic value. That is, there is no such thing as value that's independent of a valuer. That is, to say that something is a value, you must identify "to whom" and for "what purpose?" To say that something is an
objective value, you must be able to identify the facts in reality (vs. feelings) as to why it serves that purpose for that individual.
Gold has multiple objective values. It has functional values in the form of conductor, tooth fillings, etc. But gold also has an aesthetic value too. For more on the aesthetic value of gold, please refer to this article.
