Calling All Milkglass People

So, according to my research, this is a creamer or sauce pitcher by Indiana glass in the "grape and leaves" pattern. Am I right so far? What I don't understand, though, is that I see lots of milkglass items referred to as "grape and leaves" that don't look like this. Are there many grape and leaf motifs? This item is a creamy opaque milkglass...how does this compare to the more translucent varieties? The value for something like this appears to be all over the place; the condition is as near to mint as one can get. I thought $20 was a fair price, but now that I did an Etsy search, it seems $10 is more reasonable. Bummer. All thoughts are appreciated!!
