Looks like pyrite. It is not unusual for clasts (some kind of foreign material) in limestone to become pyritized. The thin pyrite coating takes the form of whatever it has adhered to, which is why it doesn't look like the typical pyrite samples you would see for sale at a rock and mineral show.

Any way of determining it's density (gms/cc)? Might give you a hint. Does it spark when struck against a file?
Conducting a specific gravity test is pretty easy:

There will be a slight error because of the string or wire that you use to suspend the sample, but the result should be close enough to help you identify the mineral.


This is assuming that you are asking about a mineral and not a rock. I can't tell for sure which of the photos that you posted is the sample that you are asking about.
