Mechanical or Die? Leaning towards mechanical but thought I would ask for opinions. Image: 1963DD-UM.jpg 56.44 KB Report this Post to the Staff

It's either Machine Doubling or hub doubling. And this one is Machine Doubling. The doubling on a doubled die is caused by the hub in the hubbing process. Its proper term is 'hub doubling' and the result is a 'doubled die'. Report this Post to the Staff
thingee Pillar of the Community United States 2177 Posts	Posted 02/13/2008 5:16 pm ICherrypicker's 4th Ed. vol.2 pg403 paragraph 2, mentions the term Mechanical Doubling. It argues the usage of machine, mechanical and Strike Doubling. Edited by thingee 02/13/2008 5:19 pm Report this Post to the Staff
