In "The Curse of Oak Island" Season 1 finale "The Find," while searching through a swamp, metal detection expert Steve Zazulyk ran across a coin with the number "8" engraved on it. It was later identified as a Spanish eight Maravedis copper coin, most likely from the 17th century.

In the Season 2 premiere "Once In, Forever In," the coin was cleaned and examined, revealing that the year 1652 was engraved on the back. Further analysis of the coin also revealed that it had, in fact been lost, in the swamp for hundreds of years, and not something planted recently. All the signs pointed to this being a legitimate historical discovery, the first of many throughout the show.

Could this simple copper coin be evidence of hidden pirate wealth? It certainly seemed like the Lagina brothers were on the right track to uncover the legendary buried treasure of Oak Island.
