Colonel Herries was for twenty-five years Commandant of the Light Horse Volunteers of the City of London and Westminster. He died at Hastings 3rd April 1819, and was buried on the 17th April in Westminster Abbey with military honours. See Grueber, 'English Personal Medals, Numismatic Chronicle, 1892, p. 235. Grueber also states that only three specimens were struck in copper, but it has not been possible to verify this.
from British Historical Medals, Volume I, p. 237
If Grueber is correct you are looking at a numismatic rarity, one of only three of these medals ever struck in copper.
