Irish error notes are relatively rare, especially older issues. Collecting errors tends to be a niche end of note collecting and Irish error notes tend to be undervalued in terms of their relative rarity. Some error notes can be quite spectacular.
Here are a few Irish error notes.
Bank of Ireland £5 1943 missing print error. The red printing layer is completely missing from both sides of this banknote.
