Hi Alfred, Thank you for contacting Mearto with your appraisal inquiry. These vintage accordions are lovely but unfortunately, there is not much of a market for them, regardless of condition, form or history. I've checked recent prices here (https://www.liveauctioneers.com/search/?keyword=castelfidardo%20accordion&page=1&pageSize=24&sort=-relevance&status=archive), which has been useful in determining the value for this. Based on the photos and information provided, and subject to examination, this is: A vintage Paolo Soprani ivory and mother-of-pearl accordion made in Castelfidardo, Italy, circa 1930s-40s with original fitted case (DIMENSIONS) CONDITION: not examined in person but appears to be in good condition PROVENANCE: acquired in the 1940s $200-300* *represents a fair-market value for auction purposes; retail or asking price may vary. Please let us know if you have additional items to appraise, and thank you again for using Mearto.
