Quote: The 4 is master die doubling as well as LIBERTY. Question: How do you know it is master die doubling and not die doubling? Also, is master die doubling not qualified as being a doubled die? Confused!

The master die would create the same doubling on all coins made from that chain. Master die-Working hubs-working dies. This would affect a very large percentage of the coins. So you will see this commonly on several dies and sometimes over several years if the master die has an issue. While they are a doubled die, with the large percentage of dies affected from all three mints, then it would be so common to not take note of.

Master die doubling is a doubled die, the master die imparts the doubling to different dies, so with all those doubled dies, value is marginal. The doubled dies created from one die are far fewer, and command a higher premium.

I am understanding what you are saying. But I do not understand how you know that a certain coin was master die doubling...or even hub doubling for that matter.

The same way you would know any Doubled Die, it is a variety with it's own characteristics.

When you find many examples with the same doubling from different dies, (Working hub damage/doubling) then you know it was a common event. When there is a larger the number of those affected, it tells you that it is master die doubling.

Thank you CM and coop. Quote: The same way you would know any Doubled Die, it is a variety with it's own characteristics. Quote: When there is a larger the number of those affected, it tells you that it is master die doubling. I can understand this. What it means to me is that there is no way that I, as a novice, can differentiate between a doubled die, a master doubled die, and a hub doubled die. The reasons I cannot do this are:  I know of no reference which lists the characteristics of each of these types (did I miss something?)  I know of no reference which lists the known numbers of each type (how many examples would it take to qualify as being master die doubling and to be hub doubling?)
