There is kickstarter and indiegogo, but I am using Ebay

I have funded several projects on Kickstarter, including a book about the intersection of dance and baseball and a movie about women playing baseball.  I have looked at indiegogo but am not a fan of that particular model.  I am taking a trip to San Diego in June so I am trying to fund that trip by selling items on ebay.  Dodger fans check out the True 1/1 Autograph of legendary Dodger outfielder and Hall of Famer Duke Snider, relic collectors and Tony Gwynn fans that are some awesome and unusual relics of Mr. Padre available.  There are Ozzie Smith, Dennis Eckersley and Trevor Hoffman relics, inserts from various sets and an autographed card of Marvel Comics editor Joe Quesada.  Thank you for your help.  Here is a link to the items  on sale
