The Sims 3 Guide - Sunset Valley
Collectibles - Metals
There are only five metals to be found in Sunset Valley, but the most valuable, Plutonium, can fetch 1,800 Simoleons at its heaviest weight. When you first collect a metal it is dirty and must be processed to be valuable. It costs a flat rate of 40 Simoleons to do this, and increases the saleable price by a whopping 75 percent each time. It's almost always worth it therefore, except for very common metals, such as Iron, when not heavy enough to make a large profit. The prices of each metal are listed below, again varying by weight as with gems. The prices listed are the metals in their heaviest forms:
Iron: 20 Simoleons
Silver: 35 Simoleons
Gold: 120 Simoleons
Palladium: 500 Simoleons
Plutonium: 1,800 Simoleons
Plutonium can be found in a number of locations, in the woods behind Lofty Cerulean Blue Pool and right on top of the hill to the north of the map, at SimHenge.
Palladium can be harvested from the rocks around Sunnyside Strand, or the far western end of the southern beach in Sunset Valley. You may also find some in the back garden of Outstanding Citizen Warehouse Corp.
Gold is quite common, and you shouldn't have too many problems finding it. Look in the cliffs beneath the out-of-town road heading east, or at SimHenge.
Metals can also turn out to be Mysterious Mr. Gnomes, when they are analysed.
Literally a gold mine for metals and insects!
