extremely fine range, ballpark about $500. use daylight for a close shot, does it have mint luster ( shiny) & was it cleaned? PCGSPhotogradeonline will get you closer on the grade. small / large date have slightly different value
XF40 with environmental damage. Value will range between $200 and $450 depending on who and how many people want it. My guess is that it will be toward the lower end of that scale.
It is a fantastic find, but I would not bother to get it slabbed. I don't believe it would receive a clean grade, it would be a "details" coin which I don't think would help the value.
Although a nice coin, it does have some damage. It is also not a terribly desirable date. I would give it strong VF details with damage. Value is somewhere in the $75 range. I would not bother getting it slabbed, IMO.
