Hello

Was given a Jasper (pale blue)round tray 3428 Picadilly Circus about 30 years ago (Wedgewood).

Its in mint condition, in original box and original pamphlet.

What could it be worth?

Wedgewood never loses its value and is worth about what it was paid for, or replacement value today.

No 2nd 'e' in Wedgwood, and 2 'c's' in Piccadilly.
I have sold a lot of china on ebay, and the only things that sold well were basic, usable pieces like dinner plates and serving dishes.
I also found that fall was the best time to sell. Spring/summer seems to be the worst.

Right now on ebay, that item is listed for sale for $4 - 23. None have sold in the last 2 weeks. 30 years old isn't more valuable, sorry.
