slightly domed top but plain, Large 1 & 1/2" across, back shows G inside V and sterling. I found here under the American Marks V page this mark but it is ever so slightly diff. Also it says 1904-1920 would this be considered Art & Crafts style? I know I may sound picky but I'm adding notes to the cards on every silver button I own, that way when I kick the bucket hubby and kids will have info. on my collection.
