South Africa. 2017-dated coins. Just three new types

Hello, I got a BU 2017 set of South African regular coins.
wanted to upload them, but then I discovered then most coins are same as coins in last years.

10cent is same design and metrologic data as 2004 10c. but different composition. Copper plated steel, and not Bz pl. steeel
20c. is same as 2004
50c. is a new type, as it has bilingual obverse, and languages are isiXhosa and Africaans
1 Rand is same to 2005 coin
2 Rand is same to 2005 coin
5 rand is new type . It is almost same as 2005 coin, but changed position of languages: in 2005 coin to the left side of arms is English , and to the right side - Tsonga language, while on the 2017 coin Tsonga is to the left side, and English is on the right side of th Arms.

So, we have three ( 3) new coin types in 2017 South Africa regular set:
10 cent ( new composition)
50 cents (bilingual type, - Umzantsi Afrika - Suid-Afrika)
5 Rand ( South Africa - Afrika Dzonga)
