Holy Alchemy -
Your teacher demonstrated how to make an alloy.
He made brass which is an alloy of Copper and zinc.
The lab I remember had us take a penny - put it in hot zinc nitrate solution for a few minutes - then take the penny out and heat it.
Where the brass is formed - looks like gold.
Where the excess zinc is - looks like silver.
Hope this helps.

The previous two responces are wrong, some people should not be allowed to use the internet.
Your teacher exposed comman U.S. one cent pieces to the element of mercury. My 9 year old son took two such toxic works of art from a 7 year old Cub Scout last week....his reasoning, mercury kills. True, but overstated in the mercuric coated pennies.

it is a particular subject from a sequence that some corporation like the Washington Mint might positioned out to commemorate some thing. generally it wont be a super deal and wont be nicely worth lots over what a 0.5 dollar is nicely worth from that era. the only thank you to make certain is to stroll to a coin shop and ask them to grant you a concept. i don't think of it will be stumbled directly to be that uncommon or everyday. in case you desire to deliver mutually funds a stable coin shop often is the source of a stronger deal than the information superhighway or television
