The designation imprinted on United States Mint products, specifically referring to the location where a coin was produced, is a crucial identifier. On bullion pieces featuring the national emblem, this indicator can be found denoting which facility struck the coin; examples include “S” for San Francisco, “W” for West Point, or absence of a letter indicating the Philadelphia Mint. This mark allows collectors to distinguish between versions and determine rarity.
The presence or absence of such a designation, along with the specific letter used, significantly impacts a coin’s value and collectibility. It provides historical context, revealing changes in minting operations and reflecting economic or political decisions that influenced production locations. Examination of these identifiers allows enthusiasts to trace the evolution of the coin program.
