Having been a coin dealer for over 25 years means that you see a few things over time. The Saint Gaudens $20.00 gold coins pictured here had been buried in the ground. They were sold to us be a little old lady in Arizona. They were so encrusted with dirt that it took some time to clean them up for re-sale. We see coins and coin collections that have been buried every 2-3 years. The difference here was that this was the first time we encountered certified coins that had been buried.
