World Error Coins and the PDS Error System

indentThe (Planchet, Die, Striking) PDS error classification system is simple and easy to remember for collectors. It can be applied to coins around the world. This article references the PDS system for three different error coins. Keep in mind that it is possible for a single coin to have a varied combination of the three.

indentThe first coin is a planchet error and a striking error. Certified by PCGS, it is a 2017 Malaysian 20 sen struck on a smaller magnetic stainless steel 10 sen planchet. A 20 sen coin is normally struck on a nickel-brass planchet thereby making this a wrong planchet error. The reverse is a full uniface strike. When the reverse was struck another planchet was lying beneath it.

indentThe third coin is a striking error. Certified by NGC, it is a "die adjustment strike" on a large heptagon (7 sided) 50 pence coin from Great Britain.

indentThe obverse shows the slightest details of Her Majesty, Queen Elizabeth II; facing right. In this case the outline of the Queen's forehead and nose can be seen. The lower part of the Queen's hair bun can be detected. No other design details on either the obverse or the reverse are present. This 50 pence die adjustment error dates from the time period 1985 to 1997 as it is the 3rd portrait (large) of the Queen.
