Washington June 20. 06.
While visiting some parts of Europe, I thought it might be useful to bring home some specimens of the different coins I met with, some of copper, some of silver, & others of a mixture of both called billon. having then a mint to established I supposed they might furnish subjects for consideration, & sometimes imitation. to these have been since added some other coins & some medals which have occasionally come to my hands. knowing no place where they may more probably become useful, by being open to examination, than in the deposit of the A. Philosophical society, I beg leave to present them for their acceptance. they may form part of a series which future acquisitions may enlarge. they shall go with this letter by the first confidential conveyance. Accept assurances of my great respect & esteem.
