In 2000 the code again underwent a small change when the quarter switched sides with the year and there was a dot between them "Q. III" There are however inconsistencies, such as missing dots and quarter codes appearing on the wrong side of the year code.

In 1950 a new system for the date coding was introduced where the two digits only indicated the year, not the quarter hence "50" means made in 1950, this system was used in the US until 1955 and in Canada a few years longer..
It has been assumed that Parker began marking some of their pens on the trim or cap bands to allow for dating in 1970. And since the gold part of the microlayer can be as thin as about 0.003–0.3 micrometer, the amount of gold used in the process is incredibly low. 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. 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. The quarter marker changed in 1988 from E, C, L, I to III, II, I or none (last quarter) according to the below table. Using the words "Quality pen", one letter per year, followed by a quarter marker, allowing for dating within a ten year span.
