As with other recent Japanese Transformers being produced and released in Hong Kong, the MP11 Starscream will be released in HK with a commemorative coin, by Hasbro.
To get MP11 with the coin, you will need to buy from a dealer/store in HK, not Japan.

A preview of the coin has been shown off by RobotKingdom, which can be seen here.
MP11 is scheduled to come out March 31st.
