<p>[QUOTE=&quot;Numbers, post: 924605, member: 11668&quot;]The backs and faces of the notes aren&#039;t printed by the same press--they&#039;re printed in separate operations several days apart, so that the back has time to dry thoroughly before the face is printed.&nbsp; So to get an error like this, you just have to have a half-finished $10 sheet accidentally end up in a pile of half-finished $20 sheets.&nbsp; Maybe somebody picked up a sheet to inspect it and then mistakenly returned it to the wrong stack....</p><p>&nbsp;</p><p>(Much later, in the 1990s, the web-press $1&#039;s were an experiment with printing both sides of the notes at the same time.&nbsp; It didn&#039;t work so well.)[/QUOTE]</p><p><br /></p>
