how much does a personal inscription  devalue an autograph? I just read that it devalues an autograph if it has a personalinscription on it - (ie. to Jane...Mick Jagger) - Does it devalue an autograph significantly or is it just a minimal amount ? Wondering here in relation to an investment value standpoint. ty - all replies appreciated !

I have heard of Markus Brandes - what are your feelings on his reputation as an authenticator of autographs? Curious here...just trying to learn and do some homework  on this subject. replys welcomed!

thank you,

Susan
