I have a foreign coin, one side is the moon and buildings, and the other side is 50, English Malaysia, EN 1973. From which country is valuable?

This is a 50 cent coin issued in Malaysia 1973. 100 cent = 1 Malaysian ringgit. The "Star and Moon" on the back of the coin stands for: 14 star symbolizes Malaysia 13 state and government, the new moon symbolizes Islam, the state religion of Malaysia, and the building is the Parliament Building of Malaysia. The coin is made of copper-nickel alloy (white copper).

At the current exchange rate: 1 Malaysian ringgit = 1.8356 RMB, then 50 cents is equivalent to 0.9 1 RMB. However, according to the policy, foreign coins cannot be exchanged in domestic banks, so this kind of coin cannot be exchanged for money. However, it is collectible, and the brand-new one is probably worth RMB in 6 yuan in the postal currency trading market.

The picture shows 1977 version of Malaysian fifty cents, which can be compared.
