If you are bidding on uncertified coins, we explicitly encourage you to have a solid understanding of the coin market including pricing and grading standards. All coins are sold as-is. We guarantee authenticity only. We not not assign grades to coins, nor do we guarantee any implied or estimated grades. For those seeking certified coins, we can provide a great selection of PCGS, NGC, CAC, ANACS, and ICG certified specimens. To ensure customer satisfaction, we provide a 30-day return policy. After 30 days from date of purchase, returns will not be accepted.
