As a collector becomes knowledgeable, authentication becomes less valuable to provide one confidence in an autographed item. However, I too submit all my items over a certain value, that aren't already accompanied by a "name" COA, to either PSA or JSA (I concur on GAI) to help maximize value upon ultimate resale. Some day I'll either decide to move an item or die and my heirs will have to cash in on the collection. Just want to get max value when that time comes.
