I was watching world strongest man competition 2018, and there was this "Bullion toss" contest
Those huge men were throwing/tossing 20 kg to 30kg Gold bars 15 feet high. They were solid gold bars or iron bars plated with Gold ??
I'd say more of lead-gold. Lead is heavier than iron, and close to heavy as gold.
30kg gold bar would be around 1.5 millions USD worth. I doubt they'd let some bafoon throw it around
