I have a page of variants here: http://www.eurocollection.co.uk/Variants.html
It's not that clear what the difference between an error and a variant is, but if a few thousand of one type of coin are minted, then that's definitely a variant; if just one is minted that's an error - the dividing line is somewhere in between. I also prefer differences that you can see clearly with the naked eye.
I have obtained a Luxembourg €2 coin for 2002 with a Dutch edge. Has anyone come across that before?
I am looking for an Austrian 2 euro coin from 2002 with 2** around the edge instead of 2EURO***. There seems to be one photo of such a coin on the internet, if it is in fact real - http://www.attilacoins.com/errors_austria_mint.asp
Has anyone come across one?
