I am not qualified to give $ value.
It is hard to sell off a large cove of good parts and advertising and shipping is expensive and a hassel. It is same hazel and expense to haul to Nats or Carlisle. Costs too much. Only way is to decide what you want to keep of this lot, what it is worth to you.... and keep and set aside the other and sell to those parts over time to those that an drive in. How much time and how bad you want to sell off what you don't want to hang on to. Remember you will meet a lot of Mopar guys, as the word gets out and some with $$ an others that want to trade you good cars,projects, parts and maybe hound dogs!
