Selling Strange Item?

I found an item called Null's Head, here is a picture: Someone at Troms told me it was worth a lot of money. Is it okay to sell, or at least keep?

 

That's a bug with the skull metadata; Quite sure you are not allowed to sell it, I'd recommend disposing

I believe it is illegal to sell vanilla items

 

But there is no MC item called Null's Head,
Null isn't even suppose to be a legit entity in MC so I'm not so sure this is Vanilla..

 

Its still not a wynncraft item with nbt data and tags. Its a glitched head,

 

True, I kinda wonder how someone would get one like this in Wynncraft though..
And Null's Head of all things, one of the most well known creepypastas for MC..

Yes Null is also a java 'item not found' error code but if that was the case shouldn't that head have only said "null" or something to that effect rather than "Null's Head" with all correct punctuation?

 

idk, the only player with a name close to null that plays wynn is null_

 

Hmmm.. This sounds like it could be interesting..
Personally I always did like the Creepypastas about MC entities, so either way I think this is cool!
