Do you know a Numismatist?

“Numismatics is the study of coins and other currency units and is usually associated with the appraisal and collection of rare coins.” Investopedia

Numismatist“Numismatists study the physical attributes of the payment media rather than the use and function in an economy. The term numismatics is often used interchangeably with the coin collection, though it connotes more intensive study than just simply collecting coins. It could be said that all numismatists are coin collectors, but not all coin collectors are numismatists.” Investopedia

I know a casual coin collector.
