Little Brown Jug

This GW Outlet rescue looks like an old gallon sized Little Brown Whiskey Jug that was dug up from a trash pit. It is unmarked. How old guys? Late 1800's? The colors are unique, I am not sure if it was burned in a fire or if it is the colors were originally this brilliant. Also, it looks like beavers gnawed on the top, to get themselves a nip. (picture 4) I can't explain that any better. It s still dusty and I am looking for a little guidance in preservation. It is old and broken, should I polish it, or is its crust its only real appeal. I think a coat of wax would bring this thing to a brilliant shine, or I should I leave it dusty , for the next owner to polish? Was it worth saving or not, Trash or treasure?
