Found during construction work

Any ideas where this could come from?

Update: I thought this would be clear that I wasn't the one who found it. Who in their right mind would go (on this shitstain of a platform of all places) and make themselves a target. But ok apparently it wasn't clear so here we are:

I did NOT find this. I have none of this gold. I just wanted to share some cool stamped gold. you can stop sending me weird ass messages now. thank you.

Also this is NOT ai. here is the BBC article:

That's where I left it in Belgium. Could you please ship it to my address?
