Overwhelmed!

My dad lived and breathed Mopar. He has recently passed. My brothers and I decided to sell everything to keep it fair. We each had a Mopar in high school but never got into them like he did. With that said I do not know that we have the knowledge to sell them. Do we have an auction? Sell on Ebay? Sell on forums? Hire a pro? He has challengers, cudas, roadrunners, chargers, and other misc mopar and non mopar. All are unfinished projects. His shop is 120x50 full of engines, doors, hoods, etc. Any advice would be helpful.
