I believe Joy is referring to the Disneyana Fun Fair Fantasy pins.
(Just echoing Dom)
In my very, very limited experience, trading these pins definitively falls more into the category of how much you like/want these pins. They are usually very low LE, but they are not "official" Disney pins, and as such a lot of people hold them in lesser value. I did trade for two(I think) of them, and we sort of counted them as a higher LE--they're low LE, but not "real" disney pins, so you sort of handicap them a little. Does that make sense? But then I traded one away to someone who really likes them, and collects them, and it helped tip the balance for me to get my holy grail--WDCC Belle, Dreaming of a Great Wide Somewhere (one of the highlights of my trip!)
Hope this helps; the one you have Joy, seems to be one people are interested in having right now because of the sentiment behind it.
Hope this helps.
