What is an "Unknown"?

There are these things people have been auctioning called "unknown"(s) can someone tell me what they are?
Thank You

idk but my best guess is that they are illegally obtained, or random items that arent supposed to be ingame

 

Its packed ice gey nub #nohomo

 

They are really expensive I hear

 

what gamemode?

 

they name tags

 

ok...

 

They can be flowers,

Maybe packed ice,
Name tags and a few more.

 

Yeah why is that so? Just how it's coded i guess?

 

what it is is if you are in 1.8 there are blocks in there that aren't in 1.7 such as the granite and stuff so someone must have obtained one of those items while fishing... basically its an item that is in the update they are using but not the one you are using ;D

 

Those items are not yet added to the auction plugin, so that is why they are called "unknown".

 

that or what i said they got an item in their game that doesn't exist in yours
