Hello there I found those stones that my grandfather used to keep and I'm wondering what kind of stone is it ? And I can see small gold flacks on it I'm not sure of it though.
Is it precious?and it's a bit bigger than a coin
Here a picture
I feel like its a copper penguin wind chime though i could be wrong. There is a hole in the top that had a something like fishing line tied to it but it fell off.
Width: 2 inches
Height: 1 Inch
Thick: 20mm thick
Thanks in advance for your answers.
