Need advice

I have around 200 different parallels of Charles Woodson from 4 years of the same product (Mosaic). Most of the lower numbered parallels are graded PSA 9/10. Since he is a defensive player, he isn't highly sought after. Although I had a blast acquiring these cards, my interests and focus of my collection has shifted and I'm ready to get rid of them. I don't want to list them individually on ebay but I also don't want to take a huge loss selling them as a lot, because I don't think anyone would buy them all for anywhere close to what I have invested in them, plus grading fees. I considered consigning them through Goldin but there was no estimate or guarantee of what they would sell for. What would you do? Especially interested in hearing from someone who has experience selling large lots like this.
