Silly Question on selling pearl items (Character name change coupon in particular)

I was looking to get a little silver to fund some of my dream horse and upgrade endeavors and saw that there were 2 orders on the market for character name change coupons. So I bought 2 from the pearl shop to sell. Turns out I cannot put them in the warehouse nor sell them. Am I missing something here?
No big deal if it simply cant be done (after all the pearls are basically free if you wait long enough ;-) ). But since there was an order I assumed it could be done and am now left a little confused. :-S :-D
Thanks in advance for any answers.

 

There's another coupon available at Web Shop that has no limit of usage and you can sell it on Market.

 

Ah, I see thanks for the response Chiclete! If I ever do a name change I guess these would come in handy. But I am never changing my name :-D

 

Anytime!
