Random title: Double Die
Explanation: A dubious term sometimes intended to mean a doubled die coin and sometimes indicating machine doubling (because there is often a substantial difference in value between the two, a savvy buyer will be sure to determine which case is true for any coin described as such); A die with doubled device details, letters and/or numerals resulting from any of several possible differences between the multiple hub impressions during its manufacture; a coin struck from such a die
