When you are looking to buy a great coin at a great price, it is worth your while to research the dealer you are working with BEFORE you spend your hard-earned money on that coin you want. I absolutely guarantee the authenticity of every coin I sell. Should you ever buy a coin from me that I have guaranteed is genuine and you later determine it is not, I will gladly refund the full amount of your purchase price and take the coin back. Forever.
