When my father died we sold almost all of his large collection of violins plus a few violas and cellos through Amati. In retrospect it was a huge mistake that I bitterly regret. The general policy of Amati seems to be to provide as little attribution as possible, and put instruments of all different quality up for auction with starting prices as low as £10. The rationale is that instruments will fetch what they are worth, but it can work as a goldmine for dealers seeking high quality instruments at bargain prices, which is obviously not in the interests of the seller. What I should have done was consult a number of auction houses before making a decision. If I had done that I certainly wouldn't have sold my father's instruments through Amati.
