Meinradus Frank (1775 - 1840) was a German luthier. His work is considered to be good.
If it is in very good condition with very good tone, the current retail (replacement or insurance) value of is approximately $9,500. If you were to sell it, you could expect to get the fair market (private sale or auction) value of approximately 40% of the retail amount or $3,800, depending on location and actual condition.
