Need info on D.C blob top

Another score for today. Anybody have an idea of the value of this bottle ? I've found plenty of info just no ballpark price. The embossing reads ' Gerhard lang's buffalo lager Washington D.C. branch' with a trademark seal in the middle. Thanks

Very cool bottle and nice embossing! I like that it's a typical blob shape but with a Baltimore Loop closure. Odd that it's got a Lightning Stopper too.
