The 2008 film "Indiana Jones and the Kingdom of the Crystal Skull" is the fourth of the "Indiana Jones" films about an archaeologist and adventurer. The first three films were set in the 1930's and this one is set in 1957. The film stars Harrison Ford as Indiana Jones and Karen Allen as Marion Ravenwood, his girlfriend in the first film and again in this film. Early in the film, Indiana and Mutt, his son, are in Peru looking for a friend who disappeared. They visit an underground cemetery and find a Crystal Skull along with some Spanish doubloons (eight escudo gold coins) and "pieces of eight" (eight reale silver coins).

Here, he and a young man "Mutt" go to Peru to hunt for magical "Crystal Skulls." They dig into an old cemetery looking for the remains of early Spanish explorers. They find the remains, some old Spanish coins, and, of course, a Crystal Skull. The skull attracts metals like a magnet, but it attracts non-magnetic metals like gold and silver. Later the pair are captured by Russians and taken to Brazil to look for more Crystal Skulls. Indiana Jones meets an old girlfriend and finds out that Mutt is his son.

The coins appear to be Spanish gold doubloons and silver "pieces of eight" or eight reales coins. These 16th to 18th century coins were made by the millions in Spanish America. They were beloved by pirates everywhere.

It appears to be a Spanish Silver eight reale coin known as a "Cob."

She informs Indiana of the nature of his relationship to Mutt.
