The day after the Super Bowl, I recall the new football coins issued by the Royal Canadian Mint. Struck in .999 silver and .999 gold, the coins are shaped like footballs. The silver has a face value of $25 and the gold, $200. Coins are dated 2017. They are attractive looking and certainly look like prolate spheroids!
Personally, I must keep these coins in mind. They would make wonderful giveaways or prizes for a future booksigning! The hero of my new novel is a quarterback.
