  1. Since non recessed screw downs render the card as “altered”, how on earth did people preserve their cards in the 60s, 70s etc. I collected as a child in the early 70s, and i had NOTHING to properly preserve cards. When i see/bid on a psa 9 from 1972, i wonder how a card was preserved, so perfectly, before there were standardized protections. Thoughts?
