Only 400 of these were issued and I imagine there are few now left intact. Most of these have been broken up to sell the notes singly. Over the years they pop up at auction and sell well singly but also when this C109 appears intact at auction it sells not too shy off the EPM value of £450. This offer is an absolute ‘bargain buy’ at this price. It is not cheap but it is worth far more than the selling price. No charge also for UK buyers.
