Old Slug

Found this in a park from the 1880's in Massachusetts. I have a guess but I'd like a positive ID please. Thanks!

Hard to tell with the dirt on the slug - need to clean and measure with calipers for a "positive" ID...

Thanks Tedyoh. Really not a lot of dirt on it tho.

Soak that thing in a cup of boiling water and a teaspoon of oxi-clean for 10 minutes. .it shouldn't hurt any patina. ...it'll take off that brown crude...might be rifling grooves under the crud.
