How Much is this Worth?? | BIG Model Railway Valuation

My uncle asked me to help him sell his large model railway collection from the 1980s. I collected three massive boxes from him and in this video we go through it together. But what's it worth? Please leave a comment with your valuation and I'm also going to send details to a few model shops to see what they offer. Also, let me know what you think they'll be prepared to pay.
