How much is a madame Alexander doll worth?

First of all the Doll Manufacturer is Madame Alexander, they are still in business, have been for a long time, and it is a collectible hobby akin to, in a different sense, model railroading. They are an established brand. Alexandra was a Queen of England- the wife of King Edward Vii ( he of cigar fame) and a different woman- Empress Alexandra was the last Czarina of Russia, discounting Stacy, who at best would have been Czarina in exile ( she preferred the lower titular rank of Grand Duchess). So get your Alexanders right. My Aunt Marie, a retired Telephone company employee- named her cat Alexander in honor of the phone inventor- should ring some Bells.
