It would be great to see them strike a commemorative coin and sell 'em at around $10 a pop, and rake in the dough.
Years back, I bought one made from the propellers of the USS Olympia (Span Am War) and feel I have a nice piece of history.
I like your idea of a bronze coin.
I did some work years ago in the dry dock in Bremerton - working underneath the USS Constellation. They had the entire thing sitting up on wooden timbers. The juxtaposition of this huge “modern” steel warship being supported by wood was weird - and then walking (hunched over) below her doing work.
They were stripping her before heading her out to be salvaged. The propellers were already off.
