I would need to find the article, but there was something in the news about how the U.S. Currency is not appropriate for blind people and there is no reason why the bills should not be different sizes or have raised lettering. It was not said if the verdict would be challenged, but we may have different sized notes in a few years.
i doubt they will use raised dots, in a past article, the bep mentioned that the raised dots 'could' eventually disappear. If the bep decides not to apeal the courts descision, then i would think we would see possibly different size,shapes or possibly maybe even holes in different positions?! lol
