Re: Court: Paper money discriminates against the blind
I spent some time in a country that had currency like that. It was really weird at first but you get used to it. But the changes in size would have to be significant enough to be able to tell a real difference. That means the $1 would have to be really small, the $5 bigger, the $10 even bigger, etc, and something like the $100 really big. That part seems kind of impractical.
Maybe they could try hole punching Braille numbers into the bills, or something else like that.
