Machine Doubling Deffinition:
 Doubling of details resulting from loose dies during the striking process (much more common and much less valuable than die doubling).
Deffinition 2:
Mechanical doubling, also called machine doubling or strike doubling, a form of doubling which appears on a coin and is easily confused with doubled die strikes. On a true doubled die coin, the doubling comes from a mistake in the process used to make the coin die itself.
