I think if you send both of these coins in to either of the grading companies a few times you will probably get both graded as a 65 or 64 or vice versa, thats just my experience with the
TPG's depending on how many coins the graders already looked at before grading these coins. The grades are not set in stone and they will grade a point up or a point down just depends on how much money you want to spend on the coin to get the grade you want when it comes to uncirculated coins. They are both nice coins.
