The product is a circulated 1861 S Seated Liberty Silver Half Dollar with a denomination of 50C. It was struck in San Francisco with a fineness of 0.9 and is composed of silver. The coin is uncertified and ungraded, and was produced during the Business strike type.
This coin came from a large old collection from the 1960's and 70's. I will be selling a lot of capped bust and seated Liberty half dollars, so make sure you check out my other listings. Eventually, I will also start selling silver dollars. Good luck on your searching and let me know if you have any questions!
