You've made a terrible mistake. Agreed, you should keep them. They're already paid for and all. You never know when a trend will start again and they could be worth $$$. Look at vinyl records. I've saved my 'Pet Sounds' and other albums. I think what hurt the baseball card market is the influx of other companies who simply milked it dry by flooding it. They subdivided into so many different categories, they drove prices down. I have 6 of the famous Billy Ripken 'f**k face on the knob of the bat' card, only because an Orioles friend got so many in Baltimore. Topps was King, but now I don't know where they rank. They put out a coffee table book years ago with all their cards from the beginning. Very cool to see some of the all time greats. What killed the sports card market wasn't an influx of other companies, it was the 80's when cards from the 50s and 60s started to become valuable, so more people wanted in, so Topps, Donruss, etc. started mass producing all their card sets. Each set had about 800 cards in it, and you could buy the entire thing for about $20. They mass produced millions upon millions of cards. The only cards that are worth anything in that era are the rookie cards of elite ballplayers (specific rookie cards, not any old rookie card) or error cards (Frank Thomas' No-Name-On-Front Topps rookie card or the infamous Billy Ripken [expletive] Face card, for example). Then they started producing insert cards, which were more difficult to obtain, and as such, more valuable. It wasn't until they realized they were overflooding the market with a mass quantity of cards that they started making a limited release, which is why cards today are so expensive. Full common sets are still there, but no one really wants them. The specialty sets all have limited runs, which makes cards even more valuable. I pulled a card out of Topps Triple threads that had 6 pieces of Ty Cobb's bat in it (or one piece layered under a 6-piece cutout). It was one of 200 cards. I thought "I'm putting this in a safety deposit box" but the price guide said it was only valued at $200. Why would a card that has pieces of Ty Cobbs bat, where only 200 are made, be valued at only $200? Because there were only 200 made of that particular card in that color (Brown). there were 150 made in purple, 100 in blue, 75 in red, 50 in green, 25 in yellow, and so on and so forth. all in all there were probably closer to 750 cards. And the reality is there's gonna be more cards with pieces of his bat in it later in life. It wasn't entirely unique. I sold it for $150. They also have signature cards now, lots of autographs out there... but what they mostly do is send packs of stickers to ball players and they sign each sticker then they stick them on the card, so they'e not actually signing the card. They've figured out how to mass produce their value, is what it amounts to. And with the advent of grading scores, it makes cards even more valuable. a Ken Griffey Jr Upper Deck rookie card, without grading comes in at about $60-$80 (haven't checked in a while). I've seen them go with a perfect 10 grading for as high as $2,000 It's no longer a kids hobby. It's expensive as [rackum frackum]
