I plead ignorance.
Not knowing when I started out these were tinkered, not knowing the pricing of stuff as a newb (did any of us). A little fellow gave my High Elf pally one of these. As a newb 'He was like Woh....and I was like Woh....and he was like woh.' Needless to say I then found out to set up as trader and priced my new Uber item at 1000pp.... and it sold.
To who ever bought it I apologise and it was a long time ago.
