Was looking through this Irish based sales site and found this. Is the seller having a laugh or is it actually worth that? http://www.donedeal.ie/for-sale/others/2369818
If anybody is dumb enough to pay €900 for that piece, then it is indeed "worth" it. That coin has a total mintage of more than 4.6 million. I don't know of any Irish ToR error coins that could possibly be worth that much ... Christian
