Cleaning a ship's hull in Galveston, I found a 1978 penny stuck in the growth
I was working a hull cleaning job on a container ship and my scraper hit something solid in the thick barnacle layer. It turned out to be a perfectly round, green penny from the year Jimmy Carter was president, fused into the shell of a big mussel. Has anyone else pulled up weird old coins or small objects from underwater jobs?
Honestly that sounds like a total waste of time. You're just finding old trash, not some cool historical piece. It's a penny covered in ocean gunk, not a treasure chest.
Thing is, if it IS Jimmy Carter era that penny could be worth something someday if it's a rare error coin. Gunk or not, you don't know until you check the date and mint mark.
