Anyone Know of a Decent Memorabilia Appraisor?

[catman]

I'm looking for someone to appraise my autograph collection, for insurance purposes. I have some very good pieces -- Ty Cobb, Mickey Mantle, Ted Williams, Joe DiMaggio, and many others. They are all authenticated or I personally saw the autograph signed.
Any ideas?

How would you go about getting something authenticated?

Or is there a way to do so if the signature wasn't witnessed by anyone in an official capacity?

Being authenticated and personally having seen them being signed are 2 different things. To maximize the value of your collection you need all of them to be authenticated. A good place that authenticates is spenceloa.com. As far as the value, you can ask them or steinersports.com.
