If I understand the question. The One Cent coins (penny's) are the longest issued denomination of U.S. coins. None were issued in 1815. Cents have been made at the Philadelphia Mint from 1793 to 2014. We have had penny's for 220 years.

The US Half cent and the US Large cent were both first minted in 1793 and were the first coins issued by the US Mint.
The first US quarter was minted in 1796. It had a portrait of Miss Liberty on the coin.

There were no US coins minted in 1776.

The mint is the place where the coin was made. In the US there are several. If the coin has a D next to the date, it was minted in Denver. S is for San Francisco.
The first US Dollar coin was minted in 1794.

No such coin was minted by the US mint.
On the "heads" side of US coinage there is a date, that tells you when the coin was made.
If you mean the coin with the lowest denomination, since 1857 it's been the 1¢ coin, commonly called a penny.Prior to that year the US also made half-cents which are the lowest-value common circulation coin ever minted in the US.
If there isn't a mint mark on a US coin, usually it means that such a coin was minted in Philadelphia.
Check that coin again. The U.S. has never minted a two dollar coin.
