I attended my local IBNS Chapter Meeting on Saturday. There were stories of a number of forgeries appearing in circulation. There are Scottish £20 notes that are quite prevalent as well as some £50 Polymers. Also, the putative ‘Errors’ in new Polymers are invariably doctored notes by the use of acetone. I saw one on Ebay as I looked for an example. A £20 polymer was almost uniface and listed as an error but it is in fact a note that has been tampered with. The seller is looking for £120 so any buyer will be conned. Any error polymer is more than likely a forgery. Caveat Emptor.
