Depicts the Archipelago Sea, with designer's initial (e). The design of the coin is based on a photograph taken by Hannu Vallas.

The Archipelago Sea (Finnish: Saaristomeri, Swedish: Skärgårdshavet) is a part of the Baltic Sea between the Gulf of Bothnia, the Gulf of Finland and the Sea of Åland, within Finnish territorial waters. By some definitions it contains the largest archipelago (island group) in the world by the number of islands, although many of the islands are very small and tightly clustered.

The larger islands are inhabited and connected by ferries and bridges. The Åland Islands, including the largest islands of the region, form an autonomous region within Finland. The rest of the islands are part of the Southwest Finland region. The Archipelago Sea is a significant tourist destination.
