Good question as I have a set of these myself and I am considering having them graded. So far, I have held off. First, the goldine and silver ones tend to bring more money. My gut tells me it depends on the grade. Many are high grade, so at MS-67 or better, it would seem to be a no brainer to have professionally graded before you sell. Below that, its anybody's guess. I cannot tell from your pics. The bottom pic looks like it has spots, which I suspect would limit your grade to 65 or less. In that case, it likely isn't worth the money.
