Trade weight or something else?

Found this in a gold camp area where I've been digging stuff from mid 1800's to early 1900's. It's diameter is 2 3/4 inches and it weighs 1.2 pounds.

I thought it was a 1 pound counterbalancing (1 pound) weight at first but it has a lip on it so that doesn't make any sense. Looks like steel cased lead. Maybe it fit on top of something. All ideas welcome even the off the wall ones!

It's a Pan Weight (Not just for trade, as those tend to be Govt regulated, but could be used like that).
The give-a-away is the hole in the base to adjust its weight. Dig out the lead or put a bit more in.

Counterweights have such a distinctive shape to them, you can almost I.D. them from a mile away.
The only examples I've ever found were cast in bronze.

Nice find,
