According to Chris Jones' barber shop collector's book, old shaving brush values can range from $5.00 to $10.00 for synthetic handle styles, and $25.00+ for pre-1900 natural handled models. Carved ivory, silver, pearl, or stag could be valued higher. Value is also determined by amount of remaining bristles, which in this case would be complete.
Mr. Jones' book is from 1999, so values may have increased somewhat. But this should give you a starting point.
Your brushes are most likely post-1900.
Also, the bristles on these look like what was called "french bristles" in the old catalogs. Exactly what "french bristles" is, I do not know. The preferred bristle then, as today, was badger. (Edit: did a little web research and best I can tell, "french" bristle is a certain grade of boar bristle.)
