Par value, or face value, refers to the nominal worth assigned to financial instruments such as stocks, bonds, or currencies at the time of issuance. In finance, it acts as a reference for pricing, legal capital, and redemption, although its importance has waned in contemporary markets. Thinkers such as David Ricardo and John Stuart Mill examined value in terms of utility and relativity, whereas John P.
Jones highlighted its subjective character, distinguishing it from objective standards. Thomas De Quincey criticized the merging of real and nominal value, and George Edward Moore connected value with ethical judgment. These viewpoints illustrate par value’s function as both a technical standard and a conceptual framework for comprehending economic exchange, demonstrating its lasting relevance in financial theory and application.
