Globally Harmonized Communication System (GHCS) is the on-line classification and labeling of collectible items, created by Dmitriy Litvak. It is designed to bond various classification and labeling systems used in different countries, or created by different authors – in ONE, globally recognizable level.


What is the GHCS?

The GHCS is an acronym for the Globally Harmonized Communication System of on-Line Classification and Labelling of Collectible Items.

The vast majority of countries already have several systems in place for cataloging and labeling of collectible items. These systems may be similar in content and approach, but their differences are significant enough to require multiple classifications for the same item when marketed thru the printed catalogs.

In different countries, or even in the same country,these issues are covered by different authors. This leads to the vague meanings, as well as creating extensive burdens for users and other enterprises in a kind.

The GHCS itself is the some kind of standard which establishes basics of cataloging and labeling of collectable items based on scientific classification. The elements in the GHCS supply a mechanism of universal cataloging and labeling systems, governing on-line catalog, and providea new level of communication between collectors.

The GHCS is a system for standardizing and harmonizing the classification approach. It is a logical and comprehensive approach to:

  • Describing collectible items with unified rules;
  • Creating classification processes for on-line cataloging, as well as labels;
  • Communicating information within community.
  • Presenting information in a manner that the intended audience can easily understand


By adopting the GHCS, authors in different countries will implement it through their own procedures rather than simply incorporating the data of the GHCS into their systems. Thus the GHCS provides them with the unified “building blocks” to help them to modify existing systems.

Why was the GHCS developed?

Comprehensibility is challenging for a single culture and language. While the existing systems are similar, they are different enough to involve multiple “labels” for the same collectible item both within any certain country and in international use. Even in U.S. there are numerous auction houses, which are having different requirements for items definitions, as well as, for information to be included on “labels” or Universal Indexes Notebook (UIN).

Numbers of classifications and labelling systems, each based on subjective opinion of authors exist at the national, regional and international levels. Eventually, all of them will collapse because of their numerous mishandling issues.

The classification of collectible items and communication between fellow collectors are fundamental to any hobby. Having freely available information on the “properties” of items, i.e. their cataloging indexes allow their selling, buying, use and managing much easily.

The management of any kind of hobby should include system, through which collectible items are identified, and which helps in communication between all who are potentially involved.

How was the GHCS developed?

While studied the tasks required to achieve harmonizationI concluded that there were three types of cataloguing systems that needed to be harmonized to achieve a global approach.

No authors still covers all aspects of classification and labelling, so, to develop a system thecomprehensive scope was required.Some factors that affected the work were included:

  • Different philosophies in existing systems on how and what should be communicated (labeled);
  • Language differences around the world;
  • Ability to translate description of items meaningfully and uniformly.

There are two existing systems (Figure #1.1) whichI’m considered as a major.Their requirements were examined as appropriate, and taken into account as proposals were developed.

  • 1-D System (Linear System).There are practically all existing systems, except 2-D.

  • 2-D System. There are only two of them. “Banknote Book”(BB) by Owen Linzmayer, and “BANKNOTER” by Dmitry Zagorenko.

I created a set of key guiding principles of the Harmonization Process:

  • Updates will not require anymore;
  • Will be based on essential properties of collectible items;
  • All types of collectible items will be covered;
  • All  parameters of system will haven’t to be changed;
  • Simplicity and intuitivefactor must be addressed;
  • Must be technologically advanced, and preferably located on-line;
  • Keep the system up-to-date, as necessary;
  • Make the system available for worldwide use.

When will the GHCS be implemented?

There is no implementation schedule for the GHCS. It is likely that different systems/authors will require different timeframes for GHCS implementation. Existing systems will need to consider phase-in strategies for transition from their current to the new GHCS requirements.

What are the benefits?

The basic objectives of GHCSare:

  • To ensure that the fellow collectors and the companiesin kind are provided with adequate, reliable and comprehensible information of collectible items;
  • To receiving benefits from technology advanced environment, and moreeffectivelycommunicate within society.
  • To let fellow collectors to minimize “lost in translation” factor, resulting in reduced misinterpretation, and to increasing the value of communication between them.

Are all collectible items covered by the GHCS?


The GHCS covers all collectible items. There are no any exemptions from the scope of the GHCS.

How will the GHCS impact existing catalogs?

The GHCS is a voluntary system that imposes no binding treaty obligations on any authors (catalogs).For authors and catalogs with existing systems, who want to implement GHCS it is expected that the GHCS components will be applied within the framework/infrastructure of their existing schemes.

However, the existing schemes will need to be modified to be consistent with the harmonized elements of the GHCS.All cataloging numbers should include“E” numbers at the beginning of numbering block.

For instance:

Existing cataloging number – P123a.

Modified to be consistent with SHCS -E45d7 (P123a)

What is the UIN ?

The Universal Indexes Notebook (UIN) provides comprehensive information for use in communication between users and “e-workplace” management. Fellow collectors use the UIN as sources of information about collectible items.

Information in a UIN also provides a source of information for other target audiences such as those involved with the professional use and consumers.

The UIN containing of 7 (seven) headings:

    1. Citation from the “MAIN TABLE” pertaining to this item;
    2. “Printers” table;
    3. “TYPE-variations” table;
    4. “Issuing Authority-Currency”  table;
    5. Transferring table;
    6. Additional information (text format);
    7. “Price Advisor” table.
