When I collected as a kid (62-67) I sorted my cards by team and held them in place with rubber bands and stuffed into shoe boxes.
Today most of my cards are stored in 800 count boxes. The three binders: One holds my T206 collection, one holds Topps inserts (coins posters etc) and the other holds some over sized oddball stuff. The "Super Shoe Boxes" hold cards from sets I'm working on (mostly non-sports stuff). The four "taller boxes" hold graded cards (mostly SGC T205 set I'm working on).
Stored on shelving behind my "false wall first line of defense against theft system"
