Good morning, Marjorie,

Thank you for contacting Mearto with your appraisal inquiry.
Noritake - vintage or antique (more than 100 years old) - sets are averaging about $1-2/piece at auction these days. The Morimura "M" mark dates to the 1920s and 1930s, which is consistent with the provenance as you've described it. I'm not sure of the precise pattern name but it likely has "rose" in the title. If this service includes tea or coffee pots or other pieces not mentioned, the value could change slightly.
Based on the photographs and information provided, and subject to examination, this is:
