Sunken Silver is a 1925 American film serial directed by Spencer Gordon Bennet and George B. Seitz.

[1] As described in a film magazine review,[2] Brice, a secret service agent, seeks information regarding stolen silver which disappeared from the government in 1804.

Hade and Milo seek the fortune for themselves, as do the "Conches," natives of Florida since the time the loot was buried.

After they have returned to Claire's home, Milo advances on Brice just as the Conches attack the house using a secret tunnel.

Hade is arrested, but escapes only to meet his death wandering in the Everglades.
