Full rims and generally sharp strike except for a diagonal part just below the crown / on the bust, aligned with light adjustment marks on both sides (as well as a single deep line on reverse), muted luster, bold overdate that is listed in Gomes but not in LMB (formerly Russo) or KM, hence probably rare, popular type (known as a dobra) that has the distinction of being the largest regular-issue gold coin made in the Americas.
