I purchased a number of autographed pictures with authentication years ago and now want to sell them but I cannot seem to contact the authentication service that originally did them.  I dont mind getting them recertified by someone currently in business before selling if: 1) there is value to them 2) they are real

I find it strange that I cant contact any of them but hey it was a long time ago.

thoughts on value and whether it is worth getting a new company to authenticate them?
