Congratulations on a beautiful find. I have yet to find even a half dollar although my two metal detecting buddies have found multiples. I don't know what I would do if I unearthed a chunk of silver that big or that gorgeous. Congratulations!!
Oh Boy! The posts above are why I've pretty much stopped posting my finds on here. I very recently dug a 1950 Washington quarter that looked like it had just been dropped and looked this way coming out of the ground. The friend I was hunting with and I were both amazed at how pretty it was and totally devoid of staining of any kind. After I rubbed a little baking soda on it the coin was gorgeous. Had I posted photos of it here I'm pretty sure the "That's a beautiful coin for a dug one" or the old "How did you get that so clean" or other similar remarks. As I've said in the past we have no way of knowing if a coin was dug, purchased, gifted, stolen or whatever. And it doesn't matter. If it's a beautiful coin compliment the person sincerely and wish them continued success. If you think it was not a dug coin well then compliment the person and wish them continued success. You should be the only one who knows if it was sincere or not.
Suppose someone takes the time to list a coin they dug and it was beautiful and when they checked to see if there were any comments they saw the ones above? I know I would be insulted. Anyway, ya'll do what you want. It just rubs me the wrong way and I'm the type of person who has to say so.
