I was recently told by someone that runs a large coin dealer (someone I recently met) -- "you are a collector, NOT a numismatist". I asked for clarification and they said, "you never made living selling coins". I referred them to this definition from Wikipedia: A numismatist is a specialist in numismatics. Numismatists include collectors, specialist dealers, and scholars who use coins and other currency in object-based research. ...and they said, "yea, that's wikipedia for you..." I've been a collector (as a hobby) since I was a kid.. I specialize in US and World coins from the 1700s and I'm attached to them because of their history. I've also sold many on eBay and I usually purchase from a few dealers that I respect. I also just started my entry into ancients but I have a huge amount to learn... My question: What IS the real difference between a collector and a numismatist? Is a coin dealer a numismatist? How do you become a numismatist? What do you study to be a numismatist?
