A variety is a claim about a coin, and claims differ in how well they are evidenced. The grade beside each says what kind of source stands behind it. This catalogue prints no valuations, so nothing here tells you what a variety is worth.

It does not tell you what the coin is worth. A catalogue can honestly report how many were struck, what metal is in one, and what the documents say. It cannot report a market price without either inventing it or copying someone who might have. So this catalogue reports the first three and stays quiet about the fourth.
