nickelsearcher Moderator United States 15395 Posts	Posted 12/31/2025 06:05 am Agree with Machine Doubling (MD). The acronym MAD refers to a coin struck with a mis-aligned die where part of the legends on either side are missing.

Errers and Varietys Bedrock of the Community United States 73798 Posts	Posted 12/31/2025 08:06 am It's Machine Doubling. Here's a good link explaining what a Misaligned Die is. https://www.cointalk.com/threads/an...coins.71781/ Errers and Varietys.

Dearborn Moderator United States 95018 Posts	Posted 12/31/2025 08:23 am Yes, MAD is not the correct terminology for this. Mad is used when a coin is struck with a die that is not properly aligned with the center on the planchets. (Mis-Aligned Die) MD is used for Machine Doubling Your coin displays MD here.
