Hi Angie, you have some nice pieces of willow...the wash pitcher is nice. That is a Wedgwood piece. The best way to find a good idea of value will be to copy and paste your items into an ebay search. You'll find the plates, cups and sauces (more common pieces) will not be worth an extreme amount. The American pieces will be worth less than say the English pieces you have (Mason's).
Thanks for visiting the site!
