Hello,My name isCustomerand I would love to help. There were no pictures that came with your question (the site has been having an issue).Please use the Add Files feature on your screen to add pictures (again, if you already have) of the item and any marks, labels or writing.
I will answer without photos for you since I do know this pattern.
The Dormant Trees pattern was made by Sango China of Japan, if the mark reads
MADE IN OCCUPIED JAPAN, it was made from 1945 -1952. If it only reads Made in Japan or Japan, then it was made 1952 to 1958.
There is no difference in value for the two marks, but those words help date the set.
A service for 8 plus some serving pieces has a current value of $200 retail.
Some sites that I recommend for selling are Varagesale.com, Ioffer.com, OfferUp.com, Ebay and letgo.com.You can also go to invaluable.com or liveauctioneers.com and search their directory for an auction house near you and consign to them.
To finish, I will need you to click the five stars at the top right of your screen and hit the green submit button, thanks!
