Antique T&V china

This is a vintage, antique set of T&V china.  We think it is about 100 years old.  It has a floral pattern, pink and yellow flowers with gold leaves and a gold trim around the edges.  On the back of the items is "T&V France".  Some of them also have "Lilly Pat July 1st 84".   We have 12 - 9-piece place settings which include 3 bowls, 3 plates, coffee cup and saucer, and an ashtray.  There are also 4 platters, 11", 13", 15", 17"; 5 covered casseroles, 2 - 9x6, 2 - 8x7 and 1 - 5x5; 5 serving bowls, 2 - 9x8, 2 - 10x8, 1 - 9x9; a gravy boat with saucer, and a condiment bowl attached to a saucer with a lid.   124 pieces in all.  We contacted Replacements Ltd to see what it is worth, but they do not have any of this pattern.  They created a new pattern number when we sent them the description and pictures.  We would like to sell the set, but have no idea what it is worth as a set or individual pieces.   Thanks for your help!
