This question is in regards to standards across the board and all third party graders but more specifically to PCGS slabs and the OGH Gen !.2 (1986-1989 ), Gen 2.1 and 2.2 Gen 3.0 and 3.1 (1990-1998) and Gen 4.4 1998-2002 ) In other words would you expect coins in the OGH holders to go up or down ?
I think you're questioning if OGH holders were under graded back then. Maybe as the technology for better glasses improved so did accurate grading. Rumblings about OGH slabs being under graded is possible.
