This set consists of 7 different commemoratives near Amaragosa Valley. There were only 450 sets minted! The denominations consist of a 10¢, $1, $2.50, $3, 2 different $5 and a $25 chip autographed by Doris Jackson (now deceased). This set is un-numbered and was sucessfully mail ordered from Doris Jackson in 1997. The $25 chip bears her autograph. Some of the events depicted were the 1960 hotel, map of Nevada, Devils Hole pupfish, power comes to Amaragosa, desert splendor, pioneer wagon tours and Doris Jackson herself. I am selling this set for $70.
