Hinkle Posted March 23, 2023 Share Posted March 23, 2023 Hi everyone, nothing to exciting lately, but a couple I've found. This one im sure is a die chip at the bottom here in the Rock. My question though is the MG designers initials, is that MD aka Mechanical Doubling. There's like a tail behind the G. Would like to get other thoughts on this.

EagleRJO Posted March 23, 2023 Share Posted March 23, 2023 It does look like MD. See the following topic which has an infographic to help tell the difference between true die or hub doubling and machine or "shelf" doubling. https://boards.ngccoin.com/topic/430263-basic-resources-glossary-for-those-posting-questions/ Link to comment Share on other sites More sharing options...
