It's an 1858-O Seated Liberty Half Dollar in AU. It is lustrous with bold details. It also has a light golden-grey toning, which I can't pick up on my cell camera. A beautiful coin with strong details. I'm glad to own her.
OK, Dave..... Either share or I am telling your wife you have a secret coin stash!! Man, another stunner. And I get weak in the knees for a lovely seated too!
She's already seen this one and the Flying Eagle Cent clashed with a Liberty Seated Half Dollar. They both arrived today. She looked at them, said "Nice but as long as you like them it's okay". So sad but true. Lol
