How much would a topps 2007 series 1 baseball gold parallel set be worth?

I recently finished up my set and was wondering how much the set would be worth. It took quite some time to get all 330 cards, and I was wondering how much the set would be worth if I were to sell them all together. Each one is numbered to 2007 and each card is in Mint or better condition. I even bought extra ones in case some were not mint.
