The offer ended in 1988 and altogether Wade produced over 5 million pigs, relatively few children were able to complete the entire set. Because of this, Sir Nathaniel Westminster wasn’t in great demand and fewer were produced. In present times, Sir Nathanial Westminster is now worth around £60 to £70. Roughly ten years later, NatWest reached out to Wade to add another pig to the series collectables. Cousin Wesley was introduced by Ken Holmes as the sixth pig of the series, released in 1999 to promote a NatWest personal savings bond for children which required an investment of £1000. As there was an initial high investment that was needed, this promotion seemed to go almost unnoticed by both collectors and investors and many people are still unaware of Cousin Wesley’s existence even though Wade produced in excess of 5000 of them. Wesley is now highly sought after by collectors who recently became aware of his existence. He sells for between £200 and £250. In 2011, Wade began a new piggy bank line with the introduction of Lady Margaret. A pink colour of Lady Margaret had been sold in Stoke-on-Trent on 3rd April 2011. The last known was in 2013 with the introduction of Wade Duke who dons a rather smart uniform.
