That's because a coin in normal circulation will also get dirty and or toned around the devices, and yet remain relatively clean on the high points of the devices and in the fields. Relatively is the key word there. A coin in normal circulation will still have some dirt and/or toning in the fields and on the devices.</p><p><br /></p><p>It's when those areas look too clean, coupled with the dirt and grime around the edges of the devices, legends, and numerals that you have to start looking closer.</p><p><br /></p><p>Also, dirt and grime in protected areas and recesses, and around the devices, but the fields and high points being very clean - that can also be a sign that the coin was dipped.
