I found out that my collection was more extensive than I thought and was almost as big as Mum's collection of 70+ items. I now have a collection of over 140 pieces of pink glass. Some is in better condition than others and there are a couple of yellow, clear and green pieces. The majority of the collection is Mayfair (59) and Royal Lace (23). I have a dozen pieces each of Old Colony and Princess.
I do have multiples within these pieces and there is only one piece of Mayfair that I would consider having the handles ground down due to a break in the handle. As I have a few of these plates, it is worth the drop in value for the increase in usefulness.
