Found this rock that the detector reads as a penny. I have no idea what it is. Any thoughts/ideas?

More info would be good!

Is iron ore found in the vicinity?

Was smelting done in the vicinity?

No iron in the vicinity that I know of. Found in central Maryland if this helps. Thx

Looks like a skarn to me. Copper skarn perhaps?
