Lefton Pitcher and Bowl - Heritage Green

[Kimmienemo]

Ok. . . So I am a little confused.  I have a Lefton Pitcher and Bowl - Heritage Green.  According to one person who sold theirs on eBay, it is a very old Victorian pattern. . . did not say old Victorian piece!

I also found the cost for replacement

I know that in previous posts, I have been informed that the prices at replacement.com tend to be high.

My questions. . . is the piece old?  What is the approximate worth of the piece?  I'm trying to figure out if I should sell it or keep it. 

Thanks

Lefton with that foil label is from the 1950s and is made in Japan. I have a piece somewhere with the same pattern. How big is that?

I think it is about 5-6" tall.  My husband liked it, so it got boxed up!  He would love this forum.  I am still interested in finding out the value, though.
