What is the value of a conn trumpet serial number 222539?

According to my records, the Conn trumpet with the serial number 222539 cannot be identified without further detail of the model. There's not enough contextual information in the provided number (model and year are notably missing). Therefore, the value cannot be established with precision.

If you require a more definitive valuation, may I recommend acquiring detailed information like year and model on this specific trumpet's serial number. With that insight, a more precise price evaluation is easily achieved through various avenues accessible.
