U.S. quarter

This image has a coin in it to indicate scale.

Do not rely solely on coins or other "common" objects for scale, as it will require people unfamiliar with it to look up its dimensions or guess, both of which defeat the purpose of the coin in the first place.

Please photograph an object such as a ruler or add a scale marking in via an image editor instead. SI/metric and United States customary units should be used (See metre, 1 E-2 m).

Examples of good practice: with (metric & U.S.) ruler and with superimposed line.
Examples of bad practice: here.
A tape measure
