I collect a few things.
I've got more than 5000 movies on tape and DVD, ranging from the old Edison shorts to newer stuff like The Hurt Locker.
I've got about 1000 albums and CDs - most of them are vinyl. Most of it is classic rock.
I do have an extensive porn collection. More than 1000 magazines, and most are now getting to the point where some are probably worth a bit: a lot of 1960s Playboy and Penthouse and Hustler from their early days in the early 1970s.
Then there are the baseball cards. That is where the madness begins.
I've every Topps complete set from 1968 until 2009. I've all sets (Topps, Donruss, Fleer, Score, Upper Deck) in the 1980s. I've every Upper Deck set up until 2005.
But, the prides and joys are the older ones. I do buy new packs now for shits and giggles, but the vast majority of the cards I go after now have been produced before 1955. I am currently trying to get all of the cards of all Hall of Famers who played in the 1950s (some cards will be tough to get, like the Mickey Mantle rookies and 1949 Satchel Paige). But, I only have 40 to go, so I am getting quite close. Pretty impressive to have every card of the likes of Aaron, Banks, Frank and Brooks Robinson, Sandy Koufax and so on.
I've also been trying to complete a 1933 Goudey set, but am missing a few Babe Ruth and Lou Gehrigs from the set.
Meanwhile, I do have four cards from the 1880s, and probably about 30 more cards made before World War II (well, that total goes to about 300 if I include the 1933 set).
I figure I could sell my entire collection for a cool million...but I didn't get them for their monetary worth, I got them because of my love for the game.
