Malaya & British Borneo 1954-1961 50 Cents Coin With Full Brockage Strike Error.
Rarity: RRRR

Mr. Tony, age 78 a very senior professional hotelier, found this undated Malaya British Borneo Queen Elizabeth II 50 Cents Copper-Nickel Coin with full brockage strike error during his early age. This coin has been in his custody for more than 45 years. He told me he kept the coin because it looks "funny".

The images above show an undated Malaya British Borneo 50 Cents Coin (Queen Elizabeth II) with a full, early-stage brockage of the obverse design on the reverse face. It represents an early strike from an reverse die cap.

A brockage is an incuse, mirror-image version of the design. It is produced when a coin is struck into a planchet or another coin. A full brockage is one that covers the entire face (obverse or reverse). The coin carrying the brockage can be struck inside or outside the collar. The brockage can be complete or incomplete. The first impression of a coin is called a first-strike brockage. If the coin sticks to a die and becomes a die cap, it will strike additional planchets. These later impressions are called “early-stage”, “mid-stage”, and “late-stage” brockages.

The sharpest, most complete first-strike brockages occur when both the coin (the “brockage-maker”) and the planchet are confined by the collar. These “mirror brockages” are highly sought-after.
