Hard to get a sense of scale from the photo, but it looks more like a camp skillet that's lost its cover. If bottom-gated, it would still be pretty old for one, late 1800s, probably. The pitting on the handle as well as the inside makes me think it was outside a long time, probably used as a planter. Looks like the tag says $75, but IMO looks too pitted to be worth anywhere near that much.
