What is this? Gold? Silver?

[aspe_heat]

I found this and I can't really figured out what it is...18k would indicate that it's gold? I'm not sure. Any help is welcome!

Dont think its gold, where did you find such a thing lol

Definitely not gold. Probably silver or something like that.

Only taking a guess from the "Trepca" stamped onto it.

I suspect that it is bismuth based on the BI stamp at the top and some images I have seen of the mineral online. BI is the periodical symbol for that element and could have been produced from the trepca mines according to the wikipedia link w130sn posted above.

Yep! After a bit more research and answers, I figured out it is Bismuth. Thanks to all of you who helped!

It has a solid price so I'll most likely sell it since I have a few of these bars now. I guess I got lucky with it!

That seems like metal or may be alloy.
