So far the earliest date coded pens found have had the code NL for 1979, and all of these pens were made in the US. Possibly anticipating the 1980 official start of date coding in France and the UK, this could have led to the presumption that the dating actually began in 1970, but proof of this has still to be found.

In mid 1934 Parker began marking most pens and pencils with a date code, both the barrel and the nibs were marked, but lacking a date code doesn't necessarily mean that the pen was made pre-1935, since many imprints have been worn off with use.

Hence a "47" marking on a 1930's pen indicate that the pen was produced in the fourth quarter of 1937, not 1947, which is a common misconception.

Flaws should always be noted, such as scratches, cracks, dents, etc.

The following codes should be used to establish an overall condition, rather than be taken literally.

Electroplating chemically adds a very thin layer of gold to the base material. The process involves physical vapor deposition of gold (PVD). According to Parker a microlaminated surface of 1.3 micrometer has a "service life" equivalent or exceeding that of a 10 micrometer gold plating.

Gold plating is usually a thinner layer than the above. In 1986 Parker patented a process, developed together with Jamers Snyder of the University of Wisconsin, for depositing microlayers of gold and titanium nitride to create the glow of gold but the durability of chromium.

The quarter marker changed in 1988 from E, C, L, I to III, II, I or none (last quarter) according to the below table.
