The question is flawed. There is no "specific value" to anything - especially not the fiat currency that you are asking others to measure it in.
The value of anything to anybody is "it depends" and all you can say from any transaction is that, at that point in time, the buyer valued something at least as much as the fiat currency they exchanged for it, while the seller valued it less than the fiat currency they received in exchange.
Value is subjective to the individual and is a ranked on an ordinal scale not a cardinal scale with all values shifting continuously based on what I currently possess, what I want in the future, what information I have and what my current physical circumstances are.
Based on my current circumstances I am not willing to purchase another ounce of gold at the current market price of ~A$1,780/oz. Why? Because I have alternative uses for my current savings that I value more.
But on the flip side, I am not willing to sell any of my unallocated at the current market price of ~A$1,780/oz (less conversion costs). Why? Because I value those holdings more than other potential alternative uses.
So, at the time of this post, the gold I currently own has a value of at least A$1,780/oz. If someone was to offer me $2,500/oz right now, no questions asked, then I would definitely part with some, but not all. So you could say that I value some of my gold at somewhere between $1,780-$2,500/oz (but value some at >$2,500/oz). However, the value to me of acquiring gold that other people own is currently way less than $1,780. I'm guessing that if someone offered me a verified ounce right now for $1,200 then I would buy it. Hence, you could say that the value of an additional ounce to me right now is somewhere between $1,200-$1,780. These indicative price ranges will no doubt change by tomorrow and again by next week, month etc.
