I'm really not sure I see a lot of gold streaks silver streaks bronze.
As far as I know it could be fool's gold or whatever that's why I'm contacting you

Daniel,

It is hard to get much detail from the photo. Pyrite (fools gold) would be a good guess.

To improve the results of the guess:

!. Where did the specimen come from? If this is known Look at a geology map> google geology map+place.

learn to read geology maps here:

https://www.rocksandminerals4u.com/geology-maps.html

The map will tell you what kind of rocks are found in that area. If the map says basaltic igneous rocks you can rule out sedimentary and metamorphic rocks.

Use some simple field tests to narrow the search, especially scratch and streak tests. Learn more about tests for identifying minerals here:
