This is Ireland 1978 3p Postage Due, Hib PD 22, SG J22. It is position 1/1 on the sheet.
There are two flaws on the stamp. The first is a mark under the word "trí" and the second is a broken "p" in "pingne".
I don't have a recent Ireland catalogue so I would be grateful if someone could confirm if the are catalogued constant flaws.
Thank you.
