6. 1880 Andrew Clemens Sand Art Bottle
Appraised Retail Value: $30,000 – $50,000 

"The owner received the sandart from his father and could not find out much about the piece. Upon appraisal, it was discovered that the sand art is a work by Andrew Clemens who was a deaf-mute from McGregor, Iowa. Clemens made these incredible pieces with individual grains of sand which became known as pictured rock. The word "pictured rock" comes from the fact that there was part of Pikes Peak national park called Pictured Rocks. And it was colored sand from the runoff from the minerals, from the rocks, that he gathered, brought home… To make these bottles. This art piece was custom made for a Miss Emma Kaufman whose name is seen on one side of the bottle."
