It can be tricky when you're first learning, I'll give you that. So many terms, so many things to remember, so many different processes and looks and effects and whatnot. But be patient, you'll get the hang of it in time.

It should be noted – “There are theories, but no definitive answers” concerning Longacre doubling. If attributable to only the master die as suggested in both theories - does not explain why the doubling manifest itself in such a diverse manner on coins from the same series in the same year. I am inclined to believe that the procedures which produced Longacre doubling in the master were also utilized in the production process of the working die. Meaning Longacre doubling can be attributable to both the master and working die.

Thanks, Viper.

As you can see from this picture, the 'doubling' to the letters is a clear outline to the letters.

Also, note that the outline is flat (as often stated: shelf like). This is important. The outline to the letters is much lower than the 'original' lettering. The net result is not a duplicate, as shown on the 1955 DDO above.

The 1955 DDO (doubled die obverse) clearly shows that both sets of numbers are the same height. This is a true classic example of a doubled die.
