What is the price of a violin labeled copy Antonius Stradivarius build by Lyon and Healy?

Lyon & Healy did not build violins that are labeled as a copy of Antonius Stradivarius. However, since violins are priced based on many factors, including age, condition, provenance, and appraisal, it's difficult to provide an accurate price without these details. If you have more information about the specific violin you're interested in, I'd be happy to help you determine a more precise price range.
