This is such a hard call: most of the collectors probably have most of a set and are looking for "fill-in" pieces or hard-to-find items, and would probably not be looking to buy a complete set UNLESS they were getting it for a child or someone else. Alot of club members collect Touraine: it is a popular pattern. Be aware that it has been reproduced though.
If you decide to sell individually, you need to be specific in sizes, condition, etc. Plates for instance came in several different sizes and some are harder to find than others. Same with bowls.
Does anyone else want to weigh in on this question?
