Greetings, Linda. First, to be clear: I’m definitely *not* the person to go to for accurate or professional clock appraisals. Small things can have a huge impact on the value of a clock or watch, and I’m basically an interested but inexperienced amateur.
That said: If the clock is a Chauncy Jerome in working order and “complete”, comparable to mine, it is probably worth between $300 and $400. If it is non functional or incomplete, it is probably still worth something: perhaps half as much. Reconditioning an old clock like this can easily cost more than the value of the clock.
