Ancient Coins are collectible Relics in Tomb Raider (2013). There are three Ancient Coins in the game.
Japanese 2 Sen Coin[]
The date reads Meiji 6, which is 1873!
Further Examining[]
One side is worn down, as if rubbed repeatedly. Maybe this was a soldier's good luck coin?
100 Mon Coin[]
This is a Tempo Tsuho. Hard to read the date, but Japan made thousands of these in the mid-1800's.
Portuguese Tin Coin[]
The Portuguese minted these in the 16th century for their colony in Malacca, which is Malaysia today. This must have come from one of the old galleon wrecks on the island.
