What does exonumia mean?
Exonumia is a term from the world of numismatics that refers to coin-like objects which are not themselves coins or currency. The category embraces items such as tokens, medals, medalets, counterstamped pieces, and scrip—objects made to resemble or stand in for money but issued for purposes like advertising, commemoration, or local exchange. Collectors and scholars of these objects are said to study exonumia, and the word typically appears as a collective, uncountable noun describing the field or its material as a whole. Though the objects themselves have been collected for centuries, the term is modern: it was introduced in the 1960s by American numismatist Russell Rulau, drawing on Greek roots meaning 'outside' the realm of coins. Exonumia remains a specialist term, encountered chiefly in auction catalogues, collector societies, and hobby literature, where it usefully distinguishes this rich side-branch of monetary artifacts from coinage proper.

Etymology of exonumia
Exonumia derives from the Greek adverb 'exo', meaning 'outside', combined with elements of 'nomisma', the Greek word for coin or money—the same root that gives us 'numismatics'. The compound was coined in the 1960s by American numismatist Russell Rulau to describe objects related to but outside of conventional coinage. Its Greek heritage links it to cognates such as 'numismatic' and 'numismatist' on the money side, and words like 'exothermic' share the 'exo-' prefix.
How exonumia is actually used
The word is used almost exclusively within numismatic and collector communities; it functions as a mass (uncountable) noun in most contexts. It carries a neutral to enthusiast connotation and is considered a technical rather than everyday term.
Easily confused with exonumia
Numismatics is the broader study of coins and currency, while exonumia refers specifically to coin-like objects—tokens, medals, and similar items—that are not legal tender.
