As Irish mail is taken to Mail Sorting Centres, it has meant that collecting the postmarks of Irish towns and villages is now pretty pointless.
There are maybe 1,400 post offices in the Republic of Ireland. Each one has a unique four digit number which is shown on the Stamps-on-a-Roll (SOAR) issued at counters.
SOAR stamps have been issued for some years and include the Marine and Animal series (updated on an annual basis), Christmas stamps, Easter Rising stamps and the most recent (2017) Historic Objects.
The stamps are often issued in unusual values.
The Mute Swan stamp was sold in the General Post Office in Dublin (the first four digits are 0235). It was #316 on the Roll. The 22cents value (well below postal rates) indicate that it was sold to “top up” a stamp already purchased.
The Goldfinch stamp was sold in Derradda, County Leitrim (5160) a very small post office.
I now have about one hundred different post offices in my collection.
