As far as I know in the days of sailing ships with muzzle loadibg guns the Navy had a set of brass plates next to each cannon. This indicated the proper place to pile the cannonballs ready for use in action. The plates were nicknamed the "monkeys paw"

No. Never heard of such. Gold and Lead have a lot of the same metal properties so it could work. They both have about same density. It would be very expensive ammunition. I don't think there were Brass cannon balls either. The guns were made of brass but not the balls.
Cannonballs are typically made of iron or steel, which can be magnetic. However, the magnetic properties of cannonballs can vary depending on the specific materials used and their composition.
Cannonballs did not exist in medieval times. They belong to a later era.

The phrase "freeze the balls off a brass monkey" is believed to originate from naval terminology in the 19th century. A "brass monkey" referred to a brass frame used to hold cannonballs on a ship, and in cold weather, the metal would contract, causing the balls to fall off. The expression humorously illustrates extreme cold by suggesting it could cause such an unusual event. However, its exact origin remains somewhat anecdotal and debated.
