first work out what you want for it and you can list it either on gumtree for free or ebay (9%) commission. or a lot of local areas have buy and sell pages on faebook
list it as pick up only ( or limited delivery if you are willing to travel a short distance to meet a buyer) and see what happens - warning thought nobody wants to pay for anything these days and you will probably only get a good price if it is 'collectable'
I would do some research first and see if you can find out what a set sells for. and go from there.
