Becareful going off of JellyNeo's prices, a lot of them are inaccurate. I'd also be careful advertising that you put the item up on the TP, especially since your username on Neopets is just about the same as it is on here. All anyone has to do is click your profile and view your program list, etc, and report you if they felt like it. Just a head's up.
It's only a R96 so you're more likely to get around the 150k mark. Jellyneo is pretty terrible with prices, unfortunately.
Put it up and wait; some avid book reader will bound to drop by and buy it from you at a low UB price. Alternatively, you can put it up in your shop for 99,999 np, then advertise on the neoboards for a quicksale. I'm pretty sure someone will grab it off you within minutes.
