1950s Larchmont by sango China

I have some china I received from my grandma and I was wondering if you could tell me what they are worth? And if there's a place that purchase china as I want the set to stay together I don't want to sell pieces separately. There's a total of 56 dishes. 

All in very nice condition, one large plate has a chip or two in it but other than that they are in beautiful condition.      

1. 8 medium plates
2. 11 tea cups
3. 8 tea plates
4. 8 small plates
5. 8 mini bowels
6. 8 dinner plates
7. 1 oval divided bowel
8. 1 large serving plate
9. 1 large bowel 
10. 1 medium bowel 
11. 1 sugar dish 
12. 1 gravy dish
