My guess is that you have a jar that is marked "Ball Perfect Mason" but that limits things dow…n to dozens of variants. Most are not worth that much but there are exceptions to every rule. Your best bet is to post a photo with a clear description on an antique bottle forum site and connect with other collectors.
