| Coin icon | This image has currency in it to indicate scale. Please add the size of the coin to this template: For example, {{NoCoins | {{convert|19|mm|in}} }} for a US or Canadian one-cent coin.
Using objects such as coins for scale is discouraged, as they will require people unfamiliar with them to look up the dimensions or guess, both of which defeat the purpose of the object in the first place. Coins are particularly bad as they can reinforce a geographical bias, and some coins' designs are not free content. In addition, some coins are protected by copyright laws in their respective countries. A further issue is that coin sizes change from time to time. If possible, upload a photograph of the subject using a ruler for scale (example) or add a scale marking via an image editor instead (example). SI/metric units are the most commonly used worldwide (see metre, 1 E-2 m).
