The product is a circulated 1921-S 50¢ Walking Liberty Half Dollar. This silver coin was minted in San Francisco and has a fineness of 0.9. The coin features the iconic Liberty Walking design, showcasing the United States' history of numismatics. This piece would make a valuable addition to any coin collection, especially for those interested in the Liberty Walking series. Its a nice coin, but I wouldn't give the grading much weight, ACG isn't reliable as a grading service.
