Crossing the Line: Shellback Series

Forged by the sea. Earned through tradition.

The Shellback Series honors one of the oldest and most sacred rites of naval passage—crossing the Equator and earning your place in King Neptune’s domain. From the first nervous “Pollywog” crossing to the triumphant transformation into a Shellback, these coins capture the salty pride, time-honored tradition, and maritime legacy carried by sailors and Marines for generations.
