Default Price Guides Alan Hager Nostradamus or........
Posted By: pas

I believe Mr. Hager patented the "arrowhead" holder with recessed corners, and that at least for a time PSA paid him license fees. I have heard he also patented the 1-10 grading system but that does not strike me as an enforceable patent.
