Over the next year, we will be selling one of the LARGEST ROCK COLLECTIONS IN NORTH AMERICA. Most of these rocks were mined and purchased in the 1970's and have remained untouched until now. WE CAN HOLD your items for several months if you are purchasing lots of rocks and you can pick them up at your convenience, but payments are due by 5PM central time within 41 days of the auction. Our next rock auctions will be July Twelfth and a huge rock auction July Nineteenth.
