Types of Error Coins-Strike Errors

Below is a definition of strike error coins by Wikipedia. Now, I suppose by now you know that a magnifying class is essential. Actually, you might need several with different magnifications. But more on that later.

Strike errors

Strike errors occur when the planchet is struck. It is a fault in the manufacturing process rather than in either the die or the planchet. A standard type of strike error is a broadstrike, where the rim image is not struck into the coin’s edge because the collar die was missing. Numismatists often prize strike error coins over perfectly struck examples, which tend to be more common, but less highly than die error coins, which are usually rarer, making it valuable.

Broadstrike errors are produced when the collar die malfunctions. The collar is the circular die surrounding the anvil (lower) die. It applies the edge device (reeded edge, plain edge) and prevents the metal of the coin being struck from flowing outside of the confines of the die. When the collar is prevented from working properly during striking, it may rest below the surface of the anvil die. All denominations of U.S. coins with a broadstrike have a plain edge.
