Don't Forget to keep your Autographs Away from a lot of Light, especially sunlight! Even reflected sunlight will take its toll. The Ideal conditions for display would be indirect lighting, at a room temperature of 65 - 70 degrees, and 50% humidity.Always check your signatures periodically for signs of fading or deterioration, and avoid excessive handling.
An official major league baseball should be worth around $100, depending on condition. RIP, Bird.
Not necessarily. A person might collect reproduction autographs too. You should be very careful about spending money for an autograph.
Ebay, Upper Deck online store, Any sports memorabilia should have is autograph, the one by my house "South Bay Baseball Cards" has probably 10-20 pieces of memorabilia with his signature, the website is http://sbaycards.com/

Humidity will ruin MNH (Mint Never Hinged) stamps. Stamps should be stored in a moisture free environment.
type in 'robert pattinson fan mail' and there should be some of his managers addresses'. If you ask for an autograph, they usually send a preprinted autograph for you but sometimes if you're lucky they actually sign it to you :)

What is Christian bales handwriting
Throw it away! its no use!
You can "hawk" for autographs at the ball park before the game during batting practice but this is not a sure thing. Your best chances is to find an autograph show where Jacoby is signing for a fee. Spend the money on a baseball, or photo, and not a baseball card. The problem is the price you will pay to get the card signed will be the same as a photo but when you try to resell the signed card you will get less back. I would recommend to have a baseball signed. It will hold it's value, and should rise in the years to come.
Some do,- some don't. If they carry an autograph, they should have glass
Difficult to say but a significant amount of money. If you have one and wish to sell it, you should contact a few specialized autograph dealers and seek their advice.
