Coin ID Please

[Kapidr]

Decided to detect in my own back yard and came up with 9 silver coins and an unknown charm?

Can anyone ID this coin? It is almost exactly the same size as a nickel.

The date is there... looks like 1783?

I thought maybe 1785? Not sure if the 8 is a 3 or an 8 and not sure of the last number.
