Euro notes are actually pretty annoying from a collecting standpoint anyway... the ECB certainly didn't have collectors in mind when they came up with them! Or maybe it's just that we're just spoiled for variety as collectors of Irish notes?
No print dates (just the year of the series I think? Open to correction on that one), no consecutive serial numbers (sequential note serial numbers differ by 9 due to the checksum calculation system used) no interesting variations (so far anyway) like fractional prefixes, overprint codes or the sterling promise (though to be fair, that one's pretty unique). The only variety really is the country serial prefix and ECB governor signature (there is also the printing code which indicates the plate and the note's location on
that plate, but that's kind of uninteresting in my opinion). Even the bloody pictures on the notes are boring... architecture styles - yawn! Though again to be fair I suppose they do need to have a pan-European theme, but it seems to me like with a bit more imagination they could have come up with something more interesting. The picture of Europa watermark also looks pretty unappealing and like it was drawn by a 3 year old.
All of that said, and to my dismay, I do still collect the the Irish serial prefix notes - more so just because they're Irish rather than that they're an interesting series of notes.
