Antique Solian ware plate

This plate has been in my family for at least 3 generations. And amazingly hasn't gotten broken. I know it's from Solian ware ,by Soho pottery in Cobridge England. And is stamped ( see photo),but the stamp doesn't look like other stamps I've seen in my search of this company and It has a hand written number 16 ,and the the letter "B" on the back . The edge of the plate is gold plated and the back round is white crackel glaze.i believe it was made in the early 1900's, but have no idea what it's worth, if anything.
