Anything that alters the valuable card will decrease its value, even if it's a signature. Most card collectors I know collect because of the rarity of the card.

I personally don't see how an autograph would diminsh the value of the card. Say you had a Ted Williams card that has a value of $3000. Then having it signed would only increase the value of it.

I do know that a baseball signed by multiple people does diminish the value, unless it's the entire group of someone

[quote="The_Champion"]I was under the impression that autographs on sports cards decreases the value of the card. So I would never send a rookie card or anything that could potentially be worth any money.[/quote]

In some cases, you are correct. However if you find the right buyer who does not care and is not just looking to pick it up to turn around and sell it, then you can still find buyers. these are mostly hardcore fans of a certain player or team who will hang onto the card forever. I've stumbled upon a few over the years. Now that I'm in Oklahoma (Home of Troy) if I wanted to really sell them, I'm sure I could find a buyer.

i guess i could be confusing but it was a card show and some items are either super under priced or super over

anyway thanks

[quote="miley cyrus fan"]yup you should never send anything nice not even a cd insert the most expensive thing i send is a magazine poster a exception if you want to send a card is print out a picture of a card or send a photocopied card but hey you got a cowboy legends autograph from the pics you got i may send emmit sometime soon and possibly him i dunno.

and ya its really too bad about some of the cards you lost but atleast you bought them back and score no offense is cheap brand i was at a memrobilia show a few years back and their was a cube of the 89 rookie set for 50 cents i said if the cubes going for 50 cents how much are the cards worth my dads like troys card is in their and im like you just bought a good brand troy card and hes like your right anyway very off topic story lol.[/quote]

1989 Score is Troy's best card. You may want to go do some research on that one. And it's highly unlikely the 1989 Score rookie set was 50 cents because the Barry Sanders is in there as well. You have the 1989 set confused with another one. Troy's rookie still fetches $30+ not 50 cents. Just 3 years ago I sold a co-worker 1 of his Score and the other Proset for $100. He was a Cowboys fan and knew what he was getting.

This remains true of not only sports cards, but any TTM collecting. Do NOT send something that you can't afford to lose.

This is a classic example of you should not do unless you are prepaired to lose anything you send in the mail. Back in 1989 I sent over 10 rookie cards to Troy Aikman in the mail. I thought nothing of it then because the Cowboys were the worst team in the NFL and no one thought Troy would become the Superbowl winning Hall of Fame quarterback he was. I sold a few of the cards over the years but still retain the vast majority I sent. This was the rare exception of my younger days of through the mail's biggest payoffs. My worst experience was losing a Dan Marino ROOKIE card in the mail. Hey, you can't blame me for sending it. Why? Because when I sent it a Beckett Football Card Price Guide never existed. I've been at this autograph collecting thing for a while!
