  Yes it looks "shelfy" to invent a new term.

In recent years I have been working on a set of British coins - at least one coin from each king or queen who issued pieces that are collectible. I am also collecting at least one coin for each Roman emperor from Julius Caesar to ... ?

  Machine/Mechanical/Step/Shelf/Ejection Doubling...whatever you want to call it. Yes.

  I disagree. It is what I have heard called "Longacre Doubling." Hubs of that era usually have a shelf around the designs and lettering. It is normally polished away when the die is basined prior to use, but if they do not basin the die thoroughly the shelf can survive.
  
  Let me see if I can find a thread that explains it better.

  See this thread. The piece shows two hub impressions. Notice the outlining left by the hubs.
  
  If these were dies impressed by those hubs, and the dies were then basined (i.e., polished by being held against the center a revolving, slightly concave polishing stone), the outlining would theoretically get polished away, leaving just the design or lettering in the die.

  I think I have heard Longacre Doubling mentioned just a couple of times (max) on the forum since I joined 3.5+ years ago and I had forgotten about that term, if I even recall it correctly. I will have to do some digging and reading. Thanks for bringing it up Capt.
