Middle East / Arabic Coin 900 Gold Chi Mint What Is It?

On the top picture, the words at the ~3 o'clock position reads Dawlat Bahrain which literally translates as "Country Bahrain", at 6 o'clock the date reads 1982 - 1402, at ~9 o'clock it reads "Bayt al-Quran" which literally translates as 'House of the Quran - I am pretty sure there must be a more accurate religious translation for this phrase. The 12 o'clock position phrase reads 'The 15th Century'.

The other side has extremely stylized letter which have a rough parallel to 'calligraphy' in English. They are a religious quote from the Qur'an (Surah 15 A'yah 9 and Surah 17 A'yah 9).


Your coin is a commemorative medal celebrating the opening of the Bayt al-Quran (the article lists an established date of 1990 - but I believe it opened in 1982):

The CHI in a circle mintmark I believe indicates it was minted in Chiasso, Switzerland. I think some Valcambi gold bars have the same symbol.

Your coin sounds like it has the right weight, it should be 26mm in diameter. Pretty interesting piece.
