What mineral or rock is in a penny?

Answer 1

A penny is made up of 2.5% copper the rest is sodium and florite

Nope, current pennies (from 1982 through 2010) are copper clad zinc. Starting in 2011 the mint is debating several options from discontinuation to changing to use of a special steel alloy that is "copper colored". Before 1982, pennies were bronze alloys of various types.

Sodium and fluorine could not be use in coins!

Answer 2

Not "A" mineral, but the material it is made from is derived from several minerals. Pennies used to be made from pure copper or silver, which technically qualify as native metallic minerals, but these days pennies are made from cheaper metals like zinc, then plated with copper. price comparison in link below.

Answer 3

gold

No, gold does not make up a penny or else it would be much more valuable, and where would we get all that gold? Pennies are primarily composed of copper and zinc.

Hope it helped,

gold is not correct,
