Ancient coin made out of rock, granite?

Hello, I found this ancient rock coin or medallion that i have searched and can't find anything. It is about 2 inches round with a ridge like a coin, with symbols and what looks like leaves or figs? has some damage that is a rock like substance, like granite and very heavy. Any ideas? Sorry best pic I can get. 

Your picture is too blurry and unfocused, I can't see anything.

More likely that this is lead?

Looke like granite or stone, Looks like from the pieces chipped off, BUT very heavy and could be lead. Trying to get a better picture to show the details. will repost. Thanks

Here and clearer pics… shows damage revealing stone like chunks, as well as a seam on side like it was two pieces bonded together? 

Zinc button or old piece of furniture 

I feel we had the exact same item a few weeks ago on the forum.

was it in the end from a clock pendulum?

I think it was not a numismatic item.

what looks like stone can also be a form of corrosion.

This one at least similar looking https://en.numista.com/forum/topic141274.html

Thanks all… looks like it may be a weight for a antique clock! Go figure…I "ll have to save it to throw at something!
