I've been talking a bunch about tradebait lately, but before I started typing this, I haven't had an up-to-date, publicly viewable trade list since I started doing card shows intermittently sometime last year.
Well, if you had about 70,000 cards in your trade pile, and bought/sold cards in bulk from time to time, you'd be in a similar position. Maybe you do and you're still able to keep up, and if so, awesome, but I canna do it no more, Cap'n.
So, rather than listing EVERYTHING, which would seriously take months, give me grey hairs and never, ever be totally up-to-date, I'm going to give you a quick rundown of what I have, by company and brand. I'll be updating this regularly as I think of things that belong on here, and I think I'll throw a link to this on the sidebar.
Topps: I've got at least one card for trade from every base set year since 1969, and a few before that. I have some higher numbers from '70-73. '74-'79, I've got anywhere from hundreds of cards to thousands. '80-'85 are soft spots for me, as I moved a few boxes of that stuff in the winter. '86-'93, forget it, it's just silly how much I have right now. '94-up, depends on the year, but I've got at least 1 card for trade from every production year ('94, '96, '99 and '10-'12 are probably the years I've got the most of from these). I also probably have at least one intact complete '89 set for trade (there are 3 here, but I've picked cards out of at least one), and if you're really, really interested, I'll check.
Topps Traded/Update: I've got some of this stuff, too. '86-'90, mostly, but I do have a good amount of the last few years' update cards.
Topps Gold: I have about 300 '92 Topps Gold Winners, and a handful of '93-'94 Gold. Also have a few '08 Gold.
'11 Topps Heritage Minor League: probably about 150 of these, including the Harper. Trout just went in a trade.
Topps Mantle HR History: have around 75 of these.
Fleer: I have a modest amount of '81-'87, a ridiculous amount of '88-'91, an unholy amount of '92, and after that it gets spottier but I've got stuff.
Fleer Update: I have some, mostly '90 Update.
Donruss: I've got a smattering of '81-'86, and a ridiculous amount of '87-'91. '92, I have some singles and a complete (pretty sure it's complete, anyway) set. (I may also have an '88 set still.) Then, I've got a ton of '93s, and after that, a small amount of the later stuff.
Cramer Sports Promotions Baseball Legends: Have about 50 doubles, various series.
Leaf: a few '85-88 and '90, tons of '91-'92 and an unholy amount of '93. Some stuff from '94-up, too.
Leaf Rookies & Stars: a handful, mostly '01.
Score: bunches of '88-92, and some '93-up, but not much.
Score Select: Have a few hundred '93s, and a sprinkling of the other stuff.
Sportflics: some '86, some more '87 and a few '88-up.
Sportflics The Rookies: a near-complete '86 set's worth of singles. Forget what it's missing, probably Bonds if he was in there.
SSPC: have a spare, near-complete '76 set. Need to replace a few commons from it, unless you wanna.
Upper Deck: tons of '89-'93, not a lot between '94-09, and about 500 '10s.
Upper Deck Goudey: Still have 100 or so doubles from '07, and handfuls from '08 and '09.
Upper Deck SP Authentic: tons of '03, handfuls from the other years.
