Identifying and Quantifying Bitcoin by Age

Would it be possible to identify and quantify all Bitcoin minted at different times since its inception, and assign a value based on its age or minted "seniority"? Such as the older, the more valuable or… the other way around: the newer the more valuable given it's exponential minting difficulty.

In both cases a different "token of value" or "quantifiable/appraisal mechanism" would emerge, to calculate and measure differentially every bitcoin holding value.

This could reduce bitcoin to a 'collectible' of course, rather than a 'store of value' — however, it could also create a tiered market of Bitcoin, adding layers of analysis and speculation that are currently not present in the cryptocurrency market.
