Dug my first Spanish Reale along the coast of a river here in Charleston, SC. The sea water has done a number on it, however I am hoping there is enough detail to identify the time frame and mint. It is silver and 20mm in diameter. Thanks for the help
"The coin appears to have an "HJ" assayer's initials. That would be found on the 1 real from the reign of Fernando VII. More specifically, the HJ assayer's mark appears only on F VII's 1R coins from 1810-1816"
