A Lifetime of Learning

I hold a B.A. in Historical Archaeology from Wesleyan University, and an M.A. in Science Education from Columbia University. I have over 30 years of experience collecting and dealing in rare items, and enjoy meeting people and hearing stories about the things that they have. I publish and write articles and books on science and numismatic education.

Mary Griffiths
18-19th C American History

I consider myself both historian and educator. History has been my main passion. I have a B.A and M.A in American History, with concentrations in the American Civil War, Prohibition, Eisenhower and the Cold War, and thanontology (the study of death). Coin appraisals and collecting is my 'day' job when I'm not doing my other job; giving night time tours at Sleepy Hollow Cemetery (yes, that Sleepy Hollow). Though eclectic, in each of my jobs I am answering the questions others are afraid to ask and educating the public on a topic with which they are unfamiliar.

We want democracy to survive for all generations to come, not to become the insolvent phantom of tomorrow.

A Global Perspective

I was born in Belarus and achieved both a Bachelor's degree in English from Minsk State Linguistic University and Associate's degree in Business Administration from the Borough of Manhattan Community College. I am also a graduate of the American Numismatic Association's Seminar series, where we complete annual coursework in coin authentication, grading, valuation, and sales. I speak English and Russian fluently, which helps bridge the gap between U.S. communities and abroad.
