I auctioned off the baseball that I signed "Hank Aaron"
Why did you sign a baseball player's name on a baseball?
I just wanted to make some money.
It's wrong to sign a celebrity's name on an item and sell it. This is considered fraud and can land you in jail. Instead, you can ask your celebrity friend to sign the ball for you.
That's too much work.
Yes, but it's still fraud. Why not find some current autographs that you can save and sell later for a profit?
