Price?

[McNamara]

My father is considering selling a wine that has a label "Highest Honor The Grand Prize Awarded to Brotherhood Wine Co. by the International Jury Worlds Fair St. Louis Mo 1904" It was originally purchased in 1906 at the Don Francisco World's Fair. It is a Sparkling Wine by Brotherhood Wine Co. Incorporated made by its own fermentation. The wine is unopened, dry corked and less than half full. We are trying to determine where would be the best location to sell this and what dollar figure we might expect to get or a place to find this information. Any help in this would be greatly appreciated.
