The website's rounded figure and the annual report total agree within the website's printed precision. They still answer different questions: a final mintage against production during a fiscal year.

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.
