Please post a new question with enough details to identify the coin.
What date?
What country?
If it's from the U.S., is there a mint mark under the date?
100.000.000
The coin is made from a copper alloy not brass and is a very common coin still in circulation today and as only face value.
a penny cuz thts not tht old
like a penny or what we value as a penny
One cent. The penny would have to be at least 60-70 years old to have any real value to a collector.
brass
I would recommend against it as it is illegal, but you would need zinc and heat to turn a copper penny to brass.
it is an old currency penny like the old value of a farthing in England
Usually, unless the cork is super compressed.
Brass
Brass? No. Bronze yes. A few bronze 1943 Lincoln cents were made by mistake.
All 1962 cents were struck in bronze. Your coin has been exposed to heat or a chemical that affected its surface, and is only worth face value.
