No, I think the massive hype (although, being in Germany I've missed most of it) is enough to get the public to rally round. Anyone with some spare money probably sees the 20p's as a good investment. I doubt the story has been exposed in the USA, and if so then probably not on a large scale. Another thing that people always tell me is that the 'Royal Mint' are trying to buy the coins back for £50. This is not true, it's the so called 'London Mint Office', an outfit that love to be confused with the Royal mint, but are instead peddlers of crappy commemorative coins and re-packaged old rubbish that are barely worth the metal they are made of.
