€250?
Due dilligence should come in at somewhere over £50 (so somewhere around that value in Euros) The reason that we don't have anything larger than £50 in the UK is because of money laundering being a lot easier with larger physical currency. The €500 note was just removed from circulation because it had become the criminal's choice of bank note. I have no doubt that the €200 will probably go in the not too distant future for the same reason.
