Two banks, Ulster Bank and Northern Bank, made use of overprints on earlier issue notes to use them up as part of their Northern Ireland Issue in 1929. Only 'Belfast Issue' One Pound notes were overprinted for the Ulster Bank. Northern Bank 1929 Overprints were used on several denominations.
With the partition of Irish currency on 6th May 1929 quantities of unissued Series C Type B £1 notes were modified by means of an overprint for use in Northern Ireland as part of Ulster Bank’s Northern Ireland Issue.
There are two types of overprint. The first was a large marking on stocks of unissued notes which were already dated and numbered the text “Issued In Northern Ireland After 6 May 1929” was printed three times on each banknote. No other adjustments were made to the notes, and they circulated with their original serial numbers and dates in place. It is not known how many banknotes with this overprint were issued. These notes were put into circulation in 1929 along with the new Northern Ireland Issue.
The second type of overprint was more subtle, the addition of ‘Northern Ireland Issue’ to undated, unnumbered blank notes. These notes were then dated and numbered under the new Northern Ireland Issue (Series E), and went into circulation bearing the dates 6 May 1929 and 1 June 1929.
Three dates have been recorded with this Northern Ireland overprint: 1 Mar 1926, 1 June 1927, 1 Dec1927. Other dates might also have been overprinted.
The second overprint type was numbered and dated as part of the bank’s standard Northern Ireland issue of £1 notes. It is on £1 notes dated 6 May 1929, and 1 June 1929, and was a device to facilitate the using up of the existing stocks of unissued blank unnumbered notes..
