Re: Conn alto saxophone
Serial number indicates it is likely a 1934-35. However, you would need to post a picture of the bell and the key stack so others people on the forum can confirm the age and model.
Pricing is all over the place. I suspect that a horn in top shape can get $2,000 - $2,500 when sold by a reputable dealer and in top condition.
It looks like your horn has a nice dent by the serial number. I’m assuming other problems too. If your horn needs substantial work (more than just pads), it can cost $500 - $1,500 for repairs. Would guess that if you tried to sell it as-is, you could probably get around $500 for it.
Conn’s sound great but they don’t have high resale value.
