How much is my grandmother's Hutschenreuther set worth?

I have a complete 6 piece dining set including dinner plates, salad plates, dessert plates, soup bowls, teapot, soup turine, casserole dish, platters, teacup and saucer, gravy boat, sugar dish, creamer...

I can not find any images of this pattern, therefore have not been able to find out how much this is worth.

Any help or advice is welcome.
