You are purchasing a 1994 Enviromint Heirloom Collection Chicago Bears Superbowl XX Champions 2 Silver Coin Medallion Set featuring Walter Payton and Bears Superbowl XX Champions coins. This set includes two 1 ounce .999 Fine Silver coins with a 24K Gold Overlay for the Portraits and Bears Logo as seen in photos. Each coin had a mintage of 500 but this is one of only 100 Matched 2-coin sets made with the Gold Overlay. I am not 100% positive, but I do not think the regular single coins minted /500 had the gold overlay, only the 100 matched sets. This is set 6/100 and is a very rare set and I do not see any for sale on Ebay or any that have sold! As you can see on the Certificate of Authenticity this is the rarest one in the mintage category. It also states that this set will NEVER have a second Mintage!!  This set will be shipped securely via USPS or UPS whichever works best. If you have any questions, please do not hesitate to ask. Thanks
