If you have ever owned or seen a Beckett holder there is NO QUESTION that they are the #1 TPG for card protection. Not even close to the others. They vacuum seal the card in a "penny plastic" and the card does NOT Move whatsoever.
I love them. BUT.....................for vintage, they are not practical if you want to ever get top dollar for your cards. Sad but true. For newer cards, BGS is still #1 for getting top dollar but vintage is what most of us on here collect me thinks.
If only SGC and PSA actually took the time to maybe copy or start using similar practices, these problems would virtually disappear.
