A terrific must-own artifact for both coin collectors and good old fashioned patriots, this 1987 one-dollar proof — made of 90% silver — observes the 200th anniversary of the U.S. Constitution, created in September of 1787. This coin represents the first time the legendary document has been commemorated via coin (there was a proposal to strike a silver dollar in observance of the 150th anniversary that never materialized). The words "We The People" are featured on the obverse over a quill pen and parchment, with thirteen Americans throughout time (representing the original colonies) designed on the reverse. 1½" diameter.
