This collection of 83 coins was donated in November of 2000 by an anonymous donor. The individuals on the coins range from psychiatrists and physiologists to philosophers, biologists, and chemists. The wide range of professions demonstrates the diversity of thought that was necessary to create the field of psychology and lead to modern day psychological theories. Many individuals in this coin collection were not psychologists, but rather contributed to the field of psychology by influencing the thoughts of later scientists who in turn used these ideas to form the field of psychology. The collection spans from the earliest coin being minted in 1799 up through the most recent in 2004. The donation letter accompanying the collection reads:

11/9/00

Dear ------,

Please find attached the commemorative medals and coins. I had them appraised for -----. I would appreciate a letter from APA confirming this amount and their receipt. I am happy to make this donation but wish to remain anonymous.

Yours Truly,

-------- P.S. I got my list from Boring’s History of Experimental Psychology. This would explain the relevance of some of the more obscure people.

Boring’s History of Experimental Psychology included information on some of the subjects in the collection, but there were a few who were not listed in this text. Each entry includes an image of the obverse and reverse (when there were images on the reverse) of the coin with a brief biography of the individual, an explanation of why the coin was created, a description of images and writing on the coin, date it was minted (if available), and measurements of the coin.

Locke, Johannes (No Date)

Johannes Locke (better known as John Locke) was born on August 29, 1632 in Wrington, Somerset, England.

He postulated that the mind was a blank slate or tabula rasa. Contrary to pre-existing Cartesian philosophy, he maintained that we are born without innate ideas, and that knowledge is instead determined only by experience derived from sense perception.
