Musical instruments
Some old musical instruments are a dime a dozen, and you’re lucky if you can give them away. However, others might have some value.
Before selling an old instrument, your first stop should be the local music supply store. It might cost you a couple of dollars, but ask whether the store can give your instrument a once-over to clean it up, check for any defects and estimate a value. Then, ask if they sell instruments on consignment.
If not, contact local school music departments and let them know you have an instrument for sale. Band teachers might be happy to pass along the word to families in the market to buy.
If neither of those options works, try Craigslist.
