Two questions:
What is it about this stamp that the seller considers it an essay, rather than a regular Scott RT14c? I can't tell any difference between his image and the one shown in Scott.
And why is this seller asking far less than the catalog value, rather than the normal five to ten times actual retail value?

This is what the essay looks like (from Eric's website):

p.s. I showed this lot to Eric, and this is his response:
"I don't think it is a real stamp, the pink is much too vibrant. And it just doesn't look right."
