I'm having trouble finding this one. You can see the doubling in the date the best and in God we trust seems to be a light spread. How do I pinpoint this variety?

there are a good size group of 72 ddos but yours will never match as it is not one of them.it is VERY strong machine doubling. true doubling happens to the dies before even being put into the machines whereas machine doubling happens are they are put into it.

machine doublings comes from the dies not being doubled but happens just from variances in striking/ejection.

Thank you sir I've been out of the loop for a while just got back today you explain that in very simple terms. The hardest part I have is determining machine doubling from a real doubling

Hello Marine,

MD or Doubled Die? a lot has been said on the subject. Here is something to think about.

Let plat with Play-doh... If we take Play-doh and fill a mold of a car. take the mold off you will have a car. but if you put the mold back on the car, slightly to the side, and push down. part of the car will be smushed, flat, shelf like.

This is MD... Machine Doubling.
it is when a die bounces down onto a coin smashing a raised design. Why does the die fall and smash the coin? Theory dictates that the screws were not tightened down enough or loosened up over time.

A true doubled die is when the design on the die is doubled. This shows a design that is thicker, doubled, or larger. this leads to a coin having a design that is larger, thicker, or doubled... a DD.

So on a MD coin... the area that is thought to be doubled and the area that is the design COMBINED will equal a normal design.
on a DD the area in question will be bigger, or thicker then a normal design.

So if what your looking at is Flat, Shelf like, or smaller then a normal design? then it is MD.
If what your looking at is bigger, thicker, or double the size of a normal design? then it probably a true Doubled Die.
