I got my hands on two sets of two consecutive $50 bills. They seem in rather pristine shape, but I don't know if they're truly uncirculated or not. I'm wondering how much of a "wow" these actually are? I noticed older bills, in good shape, and with consecutive numbers, so I was impressed. But I'm easily impressed Is it worthwhile to send these in for grading? I'm pretty sure my PCGS membership covers bill submissions as well. Appreciate the help!
