I think it's worth between $1200-$1600 but I'm sure it will go for much, much more, probably closer to $2-$3K range. I agree with wanting this in a slab. There are a lot of really good fakes out there made with similar or exact processes that the mint used/uses. Not to hard to make a fake for them.
UPDATE...
I just searched for the auction and found it - it is being sold by Silvertowne, so I'm calling it real and not a fake, Leon Hendrickson (owner) has dealt with more
Morgan dollars than all of us here on CCF have probably ever handled collectively. He is a giant in the
Morgan dollar dealer world, having handled the Continental Bank Hoard as well as thousands upon thousands of bags of Morgans. If he says it's real and from his inventory that is good enough for me don't care about a slab now.
