All Bank of England banknotes have the Chief Cashiers signature and a Serial number.
As with many banknotes, there may be fewer or more of a particular type of combination of design, signature and specific serial printed, so relative rarity is a factor.
Some banknotes may have had newly devised features such as metallic strips, or the metallic strip has shifted from the centre to the side.
There may be something unusual about the printing process or the paper, there may have been a printing defect.
The note may have been a "Star" or "replacement" note.
There may be something unusual about the serial number in that it spells out a word, such as C01N, or a common abbrevation such as 1OM (Isle of Man). The note may be the first or last of a series and have all numeric characters the same, eg. 000000, etc.
Mint uncirculated notes are always worth more than the equivalent circulated note.
The majority of the Edward Elgar Twenty Pound notes all have around the same value for an uncirculated note. The notes that have a significantly higher value are "Cypher Notes" issued for the Millenium, the Queen Mothers 100th Birthday, the Queens Golden Jubilee and other commemorative occasions. The value of these notes is further increased by the inclusion of a gold or silver proof crown in the presentation package.
