This thread seems to have drifted away from the original topic so here's my contribution: Thailand Y#145 1980 10 baht commemmorative. World Fellowship of Buddhists 30th anniversary. Not very inspiring for sure (doesn't exactly want to make me rush out to the nearest temple!)
The Black Stone of Elagabal This Roman provincial coin was issued at Emesa, Syria during the reign of the emperor Antoninus Pius (AD 138-161). The reverse depicts the Black Stone of Emesa, which was worshiped in Syria as the god Elagabal. The stone is believed to be a meteorite. In Rome, the god Elagabal was also known as Sol Invictus (the invincible sun). Sol Invictus later became a major god of Rome in the 4th century, and his birthday of December 25 is still celebrated in some places.
