None of us here are valuers, and eBay do not ffer a valuation service.
This works well for me, when I am not sure of a price for my item.
So, what you can do, is to type in the exact description of the item you are selling into the Search bar top of any eBay page, and click on Search. That will bring up any seller selling identical or similar items to yours.
Then, go down the left hand side of the page, and use the filter Sold items, that will show you what some items have sold for, and may give you some idea of the price to start at, also how their items were listed, some terms from their description or titles may be handy to use on yours.
