The 50 Rupee note that the anti-corruption piece mimics has an exchange value of 83 US cents. Thus in single quantities and encased in plastic the anti-corruption note is worth more than what it mimics, at least to collectors.
Of course, you can always download and print your own notes. Because of this it will be difficult for collectors to distinguish the notes distributed by Fifth Pillar from ink-jet printed notes.
Although Fifth Pillar printed more than a million of these notes and has been distributing them for six years they have been scarcer than hen's teeth on the collectors' market. Fifth Pillar's concept of using imitation bills to discourage corruption has been widely reported. Stories appeared in The Economist (and here), CNN, the World Bank's blog, and NumisMaster. Fifth Pillar also made a video.
This note will be historically important. Collectors of paper money should consider obtaining an example.
