Is there any way to restore faded signatures on paper?

Answer 1

Restoration to any collectible should be left to the expert that has experience with that type of work, and to this day I have never heard of anyone that restores signatures.

Never retrace a signature. I have been asked this question many times. A a signature that is light or faded will be worth more than one that has been traced. A traced signature will be worthless.

Once the autograph has faded the best you can do is stop further damage by investing in a U/V protective display case or frame. Try to find a frame with 50% U/V protection. Keep it away from sun light, and chalk it up to experience. Even reflected sun light will take it's toll over time.

Always check your signatures periodically for signs of fading or deterioration, and avoid excessive handling.
