I’m hoping someone can help me out with this one. I got this one at a garage sale recently. I looked through it and noticed it has a Mark Jewelers insert. I couldn’t find any comps on it at all. I’m trying to get an idea on value before I decide to send it for grading. Thanks!

According to GPA, the last sales are 9 8 $300, 9.6 $60, and 9.4 $54 for the direct version. No MJ copies. 

Maybe someone knows the typical % bump you might see for MJ.
