I can barely see the name Georgius on three. Looks like all are British from the 1700's. No pitting, all are worn thin but some detail can be seen. The upper left coin has 1775 date and Brittania, no date visible on the others. Searched two hours in a field. The coins and a fired musket ball were found, no other coins. Will go back there real soon, hope to find old silver. ID Edge with 10" coil.
