Great Britain, brass Admiral Vernon medal, 1739, Porto Bello, ex-Adams. AC-PBvi5F. 15.51 grams, 40 mm. Nice VF with dark spots on reverse, off-center obverse, abnormally light in color due to higher copper and lead content, with specific gravity measured at 8.47, which almost exactly matches brass, but Adams' tag says only "hard metal." Tested (XRF) at 57.85% copper and 33.56% zinc (full results on small printout included). Pedigreed to the John Adams collection.
