New Here! Die Crack? Any Help Please Let Me Know!

That is not a die crack. It may be a cracked planchet or possibly post mint damage. A die crack is when the die used to stamp the coin had a crack, resulting in a raised line on the coin.

Generally, a cracked planchet does add some value to a coin. In this condition, however, I would say that it's probably not significant.
Still very cool.

A die crack would be raised ABOVE the surface of the coin. Planchet flaws like this can add value to a coin, but they can lower it also. Generally if a coin is old, scarce and expensive, a planchet defect is a minus. If the coin is fairly common and often if it is modern, it can be a plus.

Here is an example of the die break. The lines through the stars are this 1820 large cent are a continuous die break.
