Malaysia 1 Cent & 20 Cents (1970) Coins Minted At Hamburg Mint, Germany.
The Hamburg Mint (Hamburgische Münze) has been producing coinage since the 9th century and is thus the oldest coin-minting site in Germany. As one of the five state-owned mints, the Hamburg Mint now produces a proportion of all the Euro coins for the Federal Republic of Germany, as well as foreign currencies, special coins, collectors’ coins and medals. The specialists at the Hamburg Mint are leaders in the field of design and production of special coins and individual medals. It is possible to design and create high-grade medals – for collectors, for advertising purposes and for your individual wishes – even for just one coin.

Why only these two denominations ?
Why there were minted by the Hamburg Mint in Germany?
Why no more other denominations from the Parliament series are minted after 1970 by Hamburg Mint?
