7 Black dogs ND

The coin is actually a fictional coin, not a real one. There is no record of a coin with the described specifications, and the name "Black Dogs" is not associated with any real coin. It's possible that this is a fantasy or collectible coin, or it could be a mistake or misinterpretation. Instead, I'll offer an interesting fact about a real coin: The 1943 Lincoln Wheat cent is a highly sought-after collectible coin due to a mistake in its minting process. The coin was supposed to have a copper-colored planchet, but some were accidentally minted on zinc-coated steel planchets, which were meant for the 1943 steel cent. This error is known as the "1943 copper cent" and is highly valuable among collectors.
