Editing Euro coins (section)

=== Features for persons with impaired sight ===
Euro coins were designed in cooperation with organisations representing [[blindness|blind]] people, and as a result incorporate many features allowing them to be distinguished by touch alone. In addition, their visual appearance is designed to make them easy to tell apart for persons who cannot read the inscriptions on the coins.

The coins increase in size and weight with value. Of the eight denominations of euro coins, the three lowest denominations are small, resemble copper in colour and are quite thin and light. The next three denominations resemble gold in colour and are thicker as well as heavier. The highest two denominations are bimetallic, being generally larger and thicker than the lower denominations.

In general, the greater the value, the heavier and larger the coin. Copper colour identifies low value; gold colour identifies medium value; two different metals identify high value.

There are also differences within each group. The 2&nbsp;cent coin has a grooved edge to distinguish it from the 1 and 5&nbsp;cent coins and also from the [[US&nbsp;penny]], which has the same colour and diameter. Similarly, the 20&nbsp;cent coin edge is smooth with seven indents to distinguish it from the 10 and 50&nbsp;cent coins.

While currencies predating the euro were specifically designed in similar ways (different sizes, colours, and ridges) to aid the visually impaired, the euro was the first to have authorities consult organisations representing the blind and visually impaired before the release of the currency.{{Citation needed|date=January 2021}}
