Noted Weapon Poison in bank

Is this rare?? I somehow have a noted weapon poison in my bank, despite Jagex removing poison from the game.. And the fact it's noted....?

 

Jagex is more dumb than you expect, trust me, they just replaced unnoted items with noteds
However there was possibility of banking noted items some time ago, I dont know if it's patched yet
example from my bank:

 

I suppose its rare but it doesn't add any value or anything to your account, it's just a glitch.

 

They'll come around to fixing this soon enough; I highly doubt the equity of your account will raise for this reason alone.
