I suggest listing it on eBay for a modest amount and rerun the listing 3 or 4 times, if it doesn’t go immediately.
Then, if it still hasn’t sold and you are minded, consider listing and selling in smaller lots. People buy trios and smaller groupings.
I bought several small lots of Doulton on EBay, to complete a set which had belonged to my grandmother. The seller packed it in a big, strong cardboard box with lots of newspaper, it arrived safely, all in tact. She also included a couple of extra items at no cost, as I had taken so many pieces.
I think the eBay route can be time consuming.
I am sure your local WI would like it for raffle prizes. ?
