Is Selling This Legal?

I picked up Wynncraft again and 2 years have passed. When looking in my ender chest I found some strange items, so I wanted to know if I could sell those to Collectors or if I must throw them away or just keep them. Heres the picture of one of the Items:

So, am I allowed to sell this? Please, someone who is sure he knows reply to this!

 

Now that's interesting lol

It should be allowed.

 

You are allowed to keep items such as those if they are of sentimental value to you, but no, you are not allowed to sell them to other players.

It isnt a Vanilla Item, so I should be fine then?

Oh. Thanks for the answer!

 

The item falls under the category of glitched items, which means intentionally selling it will result in a ban.
