Antique Bottles

Antique bottles are truly a part of history. The different types of bottles tell a story about a particular industry or way of life. For example, medicinal bottles tell us how far the medical industry has come since many elements are now stored in plastic bags. Seeing an old glass IV bottle can take you back decades.
Geodes

Geodes or Fluorescent Minerals, sometimes called Thunder Eggs are forms in volcanic rocks where water has worn away a pocket in the rocks leaving behind different minerals in the cavity such as iron, quarts and agate. The large variety of elements that is used to create thunder eggs accounts for the differences in size and color of the specimen. No two will ever be exactly the same. The larger the mineral sample and the more colors that show will determine the value of your find. The largest geode ever found was the size of a minivan discovered in Put in Bay, Ohio.
Gold Nugget

California isn't the only state where there has been success in gold treasure hunting by amateurs. Gold has been found in North Carolina, South Carolina, Alabama, Nevada and Virginia. The gold was found with the use of portable metal detectors or gold-panning. So, there still might be gold left "in them thar hills".
Meteorites

Treasures are falling from the sky. A natural object originating in outer space that survives the impact with the earth’s surface is called a meteorite. Most meteoroids burn up when entering the Earth's atmosphere. However, it has been estimated that over 500 meteorites do reach the surface each year and they will range in size of a marble to basketball size or larger. Only about five or six will be recovered each year and pound for pound, meteorites are move valuable than gold.
If you are lucky enough to have discovered a meteorite you could get about $4.00 a gram or $125.00 an ounce. Meteorites have been found all over the world but some of the best hunting places to start looking for them include deserts and dry lake beds. Known meteorite impact areas like Barringer Meteor Craterin in Arizona and Odessa Meteor Crater in Texas can also produce good results. Meteorites have also been found in California, Kansas, Illinois, Wisconsin, Oklahoma, New Mexico, Nevada.
Morel Mushrooms

Found in the north west corner of the state near Carson City. Hunting for morel mushrooms typically runs from early April and runs through June depending on your geographical location. Moral mushrooms are found in small patches under dead or dying elms, ash, apple and even pine trees. The seem to like to hide under or near thickets or other plant small plants growing in the area but since the ground cover varies a lot each patch of mushrooms you come upon may be growing in totally different conditions. Typically the day time temperature around 60 to 70 degrees, night time temperatures not less than 40 degrees and the soil temperatures of about 50 to 60 degrees with good ground moisture levels are ideal for moral growing.
Opals

Juniper Ridge Fire Opal Mine is another mine that allows the general public to search for opals on a fee bases. The digging fee is $200 per person per day which gives you the right to dig for opals at the mine area and you are allowed to fill a one gallon bucket with raw gemstones. The mine operators at the Juniper Ridge Fire Opal Mine believe that any reasonably health and active adult should be able to fill a one gallon bucked within a single day. If you have more than one gallon bucket worth of material you can pay an additional fee or simply keep only the highest grade of opals to take home.
Turquoise rough

Turquoise is usually found sandstone layers and can be seen as splotches or as a network of brown or black veins running through the sandstone. There are many small-scale mining operations that are worked by hand. Only one mine in Apache Canyon California operates at a commercial capacity today.
In Nevada turquoise has been found in Clark, Elko, Esmerelda County, Eureka, Lander, Mineral County and Nye counties.
Happy Treasure Hunting.
