This is the follow-up publication to the author's 2020 publication, U.S. Large Cents 1793-1814 Variety Identification Guide (the "blue book"). This is the first of three new volumes which are designed in the same familiar format, though with important updates, greatly improved photos, and much more.

This guide is entitled the Professional Edition as it is primarily targeted at users who already have (or aspire to have) an intermediate or advanced level of expertise in attributing Early Date Large Cents, or who have expertise in other series and want to take their underlying knowledge of attribution methods from elsewhere into this series.

The author of this guide is not a fan of "change for the sake of change." As such, he has kept the guide in the same intuitive format, while at the same time introducing important and highly useful new features, as well as important updates and previous omissions included.

One difference in this guide and the previous 2020 guide is that the text descriptions of each die is more succinct, focusing on the unique reminders the distinguish each die, rather than extended dialogue that covers the same ground that you should already know to be using with your attributions, such as letter, leaf, and date positions. This is not to say that the latter observations are not mentioned when it feels needed, but the dialogue surrounding such observations is cut to a minimum to reduce clutter.

In addition, this guide contains markedly improved photos, dozens upon dozens of all new close-up photos, lots of pickup points not necessarily covered in the first guide, and last but certainly not least, a proprietary die staging and pricing system not found anywhere else.

The die staging system is fairly self-explanatory. It uses a decimal system, very similar to the die staging system used with Bust Half Dimes, and even somewhat similar to the new die staging system published in the Bust Half Nut Club's new book. In this guide, you will find the description of the respective die stage described for the obverse and reverse. For the purposes of attribution, whichever side of the coin is more advanced is in fact the overall die stage (ie- the more advanced side supersedes the other side).

The unique pricing system contained in this guide is very similar to the unique pricing system used in the author's previous publication from 2024, the U.S Coin Die Varieties guide. Instead of giving actual dollar amounts for the price in any particular grade for a given marriage, the value is given in relative terms in comparison to the most common (least valuable) underlying sub-type for the year (the 1794 head of 94's will be compared to the most common 1794 head of 94's, but not the Head of 93's, for example). The whole purpose for not giving specific dollar amounts is so that the price guide will stand up to the test of time much more resiliently than with specific numbers.
