I am not a coin person but reference 1 below does contain information on quarters from 1946 to 1964.
Mass = 6.3 gm
Diameter = 24.3 mm
Radius = 12.65 mm
I cannot find a reference for a 1963 quarter thickness, but a modern quarter has a thickness of 1.75 mm (see reference 2)Source(s): 1. http://www.coincommunity.com/coin_facts/quarter_do... 2. http://www.usmint.gov/faqs/circulating_coins/index...
