Need assistance identifying this

This was found during recent construction at my property on Long Island in New York.

 

It’s about 1 1/2” at its largest point .  Just smaller than a golf ball.   It has several very shinny spots that are about the size of a pinky nail.  Some smaller shinny spots are present also.   

 

Thanks in advance for any help you can provide.

 

John
