This certified coin is a circulated 1853 Seated Liberty Dime that was recovered from the SS Central America shipwreck. It has been certified by PCGS as AU50 and comes with gold nuggets also from the shipwreck. This coin was minted in Philadelphia and has a denomination of 10 cents. The Seated Liberty design was used in the United States during the mid-19th century, making this piece of history a valuable and unique addition to any coin collection. Signed and certified by chief scientist Bob Evans. Some information I have come across suggests that the weight of the nuggets is about 1.5 grams.
