Take a look at ebay completed items sold. It does appear that when I looked up Carnival Glass Peacock some of those do have some good value, but I didn't look all that much to see if I could maybe find this actual piece. I can't say if its old or not, because I was told some of the new pieces were made from the original old molds. I've seen in antique shops the same patterns of depression glass made in carnival, slag and jade glass.
