British and Irish Banknotes

North of Scotland Bank Limited, specimen £10, 18-, no serial number or signatures, printed on watermarked paper with counterfoil, two black CANCELLATION overprints, about uncirculated, the issuance of this £10 was short-lived with only a single date of issue, issued notes are unbelievably rare, so obtaining this specimen is likely the only way to complete a collection, an opportunity that is unlikely to be repeated in a long time
PMS NS 18s £800-£1,200
