Honus Wagner

Jedburgh

I just recently gained possession of a 1934 banquet card for the Mckeesport Pirates. The card was signed by several players including three hall of famers; Honus Wagner, Pie Traynor and Loyd Waner. Along with the three hall of famers the card was signed by Cookie Lavagetto and other old time major leaguers. I have been advised to get the card authenticated and am in the process of getting that done. My question is how much a card like this would be worth once authenticated. Any information would be greatly appreciated
