Hey, Spoke: Silver should be at least 10.8 X face!! so, that's .25 X 10.8= $ 2.70 -- including shipping.
Why would you buy it? Do you like it or do you think you could make money on it? Either way, you can't get a good look at the coin from the images and accordingly, buying it would be a gamble.
You can proably find a non cleaned one for about that price in that grade in a dealer's bargain bin. I'd pass on that one. Phoenix
