Nice die crack on a proof coin.... A die break would be a cud or retained cud, although some do use the term interchangeably
I'd say planchet defect.
"Machine" or "Mechanical" doubling. A natural occurrence on most dates, denominations, and types of (mostly) modern coins. This type of...
The original coin at the top of this thread was struck from false or fake dies. The '55 cent above is an example of what used to be called the...
The Dime is damaged
The 1994 coin is copper-plated. It's not an error, or struck on a copper planchet.
It's a lamination

If it's copper colored on both sides, and the reeded edge is fully copper, then it's been copper-plated.
Yes, as mentioned it's a common, minor, Mi-Aligned obv. die.......unless the obv. looks like it's off center, they usually don't bring much of a...
It's not a 'yellow-jacket' improper metal mixture planchet.
Separate names with a comma.
