First thing to consider is value after they are graded. The high grade coins have a nice value to them, but some grades even as high as PR-69 would not be worth grading. So best to look to see what the value would be first before sending them in. PCGS
shows the grades/values on the coinfacts section on there site. They don't show the cost of grading though. But if you figure they will cost about $50 to have graded, then compare examples to see if they would be worth submissions or not, that will be the first step. https://www.PCGS.com/coinfacts

So a coin like that would be worth grading. But click on lower images as the grade goes down and watch the values drop?https://www.PCGS.com/cert/07885394PR-69 D-cam Just one grade lower: $15.
To have it graded could cost as much as $50. To get back $15 would not be worth having it graded. So the expression, "Look before you leap" (Or as I say it, "Look for the cactus first") then you will save your self a lot of grief. No use having a coin graded that will cost more than it is worth. Most collectors will not pay anything extra for a graded coin. So why do that?
