How much do you think this is worth? It is a very nicely toned coin on both sides and it has a beautiful luster. I also believe that the toning has been growing - every few months, it seems to have grown a millimeter or so. What I’m trying to say is, what do you think about it’s value, and maybe if I should get it slabbed and graded or something?... Anyways, here are the pictures.
As noted by our fellow enthusiasts, it's a proof which was probably liberated from a coin folder/album. The ring on the outer rim is indicative of a proof that was popped out of an album and returned to the wild because of the tone. Most folks don't like that...especially on a proof coin so it becomes a spender. Considered to be an impaired proof I suppose. The haze may be removable based on some reading I've done here lately. You may want to do a Search on MS70 and how to use it.
