That is one nice ground found copper, errr, make that water found copper. Amazing how the water preserved the copper so well, but so many of your relics are great so why not a state copper.
I am 99% sure the variety is 1787 Maris 33.2-Z.5 variety, the key to ID was , first all the number cinquefoils must match along with colons and dots/periods, if any missing than keep looking, I kept looking and all features described in the Whitman book match for the 33.2-Z.5, diagnostic for the reverse are the dentils that without a doubt match the example description and photo in the Whitman book. 1787 Connecticut Copper - Miller 33.2-Z.5
