Malaysia Parliament House Series 5 Sen Coin (1967-1988) With Full Brockage Strike Error
Rarity:RRRWhat is a Brockage Strike Error?
First, a coin must be, for one reason or another, not ejected or otherwise removed from a mechanical coining press. Accidentally, it remains on one of the dies.
Second, while a coin remains on one of the dies, the next planchet (prepared blank) is fed into the coining press and the striking process occurs again. This next planchet then becomes sandwiched between an already struck coin and one of the two dies.
