Singapore on Tuesday unveiled a commemorative medallion ahead of next week's summit between the U.S. and North Korean leaders in the wealthy city-state, carrying the inscription 'World Peace' in large letters on one side.

The words on the medallion, featured on the online shop of the Singapore Mint, are accompanied by the dove and olive branch motif, a biblical symbol of peace, as well as a rose and a magnolia, the national flowers of the two countries.

The other side of the souvenir, which costs more than $1,000 for the version in gold, depicts two hands clasped in handshake in front of both nations' flags and the June 12 event date.
