That coin's a tantalizing clue. If it’s really from an 18th‑century merchant ship, the mint mark could tell us where it was made, maybe even its owner. The rim might hide a micro‑etch or a serial number that the crew used to track cargo. I’ll pull up some old maritime trade records and compare the coin’s design to known issues from that era. If it’s a standard issue, the story’s simpler, but if it’s a custom piece, that could mean something more—like a coded note, a secret payment, or a commemorative charm. Either way, it’s a small piece that could open up a whole deck of history. Let's dive deeper.
