The S and the 9 show it, as you mention. You can tell that this is not true doubling because there are no split serifs... it just looks &quot;smudged&quot;. Additionally, at this period of time, the mintmark was applied separately - if the date was doubled, the mintmark wouldn&#039;t be. If the mintmark was repunched, the date would be fine. The fact that both of them show the same distortion instantly proves machine doubling. </p><p><br /></p><p>As for the 54S... chips in the 9 are incredibly common across most dates of Lincolns. This is an interesting feature, but that coin, especially in that condition, is not worth a premium.[/QUOTE]</p><p><br /></p>
