All manner of concrete, steel, and stone rubble from dredging, demolition projects, and other construction is used as artificial reef materials. This material is generally available at very low cost or free from construction companies who are more than happy to get rid of it. Transportation costs determine where this material is used by the Reef Program.

Gold "Double Eagles"

These metals are of little interest as artifacts. They are, however, interesting for other reasons. Tin and zinc are used in copper-based alloys such as bronze, and the diver's favorite - brass. Aluminum, lead, and titanium are all used in the manufacture of many items of dive gear, not the least of which is tanks. And zinc is used in pure form in sacrificial anodes which protect the other metal parts of your dive boat from corrosion, while chromium and nickel are major constituents of many marine alloys. Wouldn't we all like to find a trove of silver and gold!
