I would have to dig out some old books, but IIRC, the American Arts Gold medals were in the Red Book for a few years, but were dropped??? That's my recollection, perhaps a false memory.

They are good examples of how the U.S. Mint is a day late and a dollar short to most new markets.

The Mint makes the most numismatic money selling base metal coins at a healthy premium to their face values to coin accumulators (remember that most of the base metal coins cost less than 20% of face value to produce, save the cent and five cent coins).

The ATB Five Ounce hockey pucks came about simply because some member of Ed Moy's staff saw a few older ones (from the brief days of the earlier "five ounce craze") and thought they were neat enough to try again. No knowledgeable coin person ever had this idea.
