This is a rare bottle. It would appear that the embossing is directly on the glass which is unlike the known example or two which have the embossing on an applied seal.
The best advice that I could give you would be to put it to auction with one of the specialty bottle auctioneers. See bottleauctions.com for a list of such auctioneers. Call several of them and discuss terms for consignment.
The big wildcard with regard to value is the condition. This is a bottle that needs to be examined in person by a knowledgeable collector to determine exactly what the condition of the glass is and how this might respond to a professional cleaning.
