Both look to be Art Nouveau period from late teens to about 1930 !! Look well made !! But beyond that its about all one can tell from pics !! Value would depend on what they are made of and what the public is looking for !! I would check ebay for similar and then look on the left column for sold listings !! That will tell you what people are actually paying for similar broaches !! They do not need to be the same exact one,, just similar !!
