This is a pin badge of the "SL Yamaguchi" steam locomotive, commemorating the "Railroad Day" in 2000 by JR West Japan. It is about 3cm in diameter and has a protruding front section. It was a commemorative item included with the commemorative tickets sold at the time, and has been stored in its original condition, attached to the backing card. The backing card has some minor scratches, but the badge itself is in good condition.
