Answer:
Canadian dollar - Bills are often differentiated by size for the visually impaired. Larger denominations in Australia, for instance, are both taller and wider with strong contrasting colors. Euros also follow this logic, while larger notes – like the €200 and €500 – feature tactile marks too. The U.S. and Canadian dollars are currently the only major currencies with same-size notes. The Canadian dollar, however, features tactile marks on the upper righthand corner of bills, and the notes are also different colors to aid the visually impaired. While most other countries are ahead of the U.S. in making their currencies more accessible for the visually impaired, that may soon change with a new proposed $10 bill that would be the first U.S. dollar to feature tactile markings.
