How much is 1 elk in usd?

I'm curious to know, how does one determine the value of 1 elk in USD? Is there a standardized exchange rate or is it more of a subjective assessment? And furthermore, given the fluctuating nature of cryptocurrencies and the unique qualities of elk as a non-fungible asset, what factors would influence the calculation of such a value? Is there a specific market or platform where elk-to-USD transactions are facilitated?
