Could you elaborate on the presence of mint marks on United States coins? Specifically, I'm curious to know if all US coins feature these identifying marks, or if they are exclusive to certain denominations or series. Furthermore, could you explain what information these mint marks typically convey and how collectors utilize them in their pursuits? Additionally, are there any recent changes or updates to the minting process that have impacted the presence or nature of these mint marks? Understanding these details would greatly enhance my knowledge of numismatics and coin collecting.

    The absence of mint marks on U.S. coins from 1965, 1966, and 1967 is a noteworthy phenomenon.

    These coins, unlike their predecessors, do not bear any identifying marks indicating their mint of origin.

    Among the rare coins that lack mintmarks, there exist those that are exceptionally valuable due to their scarcity.

    Additionally, there are certain U.S. coins that, according to their historical specifications, were never intended to have mint marks.

    The Philadelphia Mint, for instance, has traditionally produced coins without such identifying markers.
