I think Judge Robertson must have seen Ray:
U.S. District Judge James Robertson ordered the Treasury Department to come up with ways for the blind to tell bills apart. He said he wouldn’t tell officials how to fix the problem, but he ordered them to begin working on it.
“Of the more than 180 countries that issue paper currency, only the United States prints bills that are identical in size and color in all their denominations,” Robertson wrote. “More than 100 of the other issuers vary their bills in size according to denomination, and every other issuer includes at least some features that help the visually impaired.”
This is good news for blind people using American currency, and bad news for the US Treasury, just in case our pal Ben needs any more of that. Nothing spurs inflation like printing a whole bunch of new paper money.
