It’s a simple fact of life that every TTM autograph collector has to live with. The bigger the star, the less of a chance that they’re going to accept fan mail, simply because they get so much of it. They either have the post office return obvious fan mail to the sender, or have someone do it for them. Those are the player autographs that you’ll have to get through one of the many auction sites or at a memorabilia show, for a signing fee. The addresses stay on my lists because the addresses are correct, and signing habits do change. The overwhelming majority of athletes will sign autographs through the mail, so concentrate on those players rather than the ones who won’t sign. The best thing you can do is join a message board that lists signing successes and failures, and see what the signing habits are of the player you want to mail to. That will also increase your chances for success. In the address list is a column titled “Tough TTM” and if there is a “Y” in that column it indicates that player has less than a 25% success rate as reported as several collectors forums.
