The U.S. Constitution was ratified in 1788, but the bicentenary commemorations were staged across 1987–88, timed to the September 1787 signing in Philadelphia. The Isle of Man had by this point established itself as an aggressive producer of large-format commemorative silver for the collector market, leveraging its Crown dependency status to issue coins that circulated legally but were never intended to. The Pobjoy Mint struck the bulk of Manx commemoratives during this period under contract.
At 155 grams of .999 silver, this is a five-ounce piece — the weight doing the commercial work the denomination cannot.
