Private Market Value
Based on the information you have supplied, I would estimate the "private market value" of your piano at somewhere between {minPrivate9} and {maxPrivate10}. By "private market value" I mean the price an informed buyer and seller are likely to agree on, where both parties are private, non-commercial entities (not dealers). I suggest that you start by asking {askingPrice11}, and take any offer over {settleabovePrice12}. Keep in mind that used-piano prices are depressed in these challenging economic times, as there are far more pianos for sale than there are buyers.
