All items are sold as is with no guarantees of any kind. We pride ourselves on accurate representation of everything we sell, but it is the buyer's responsibility to make an accurate appraisal of any item he/she chooses to bid on. Currency and coin grades are not guaranteed. We go by the grading company or the packaging of the item to determine grades. But again we do not guarantee grades on currency or coins. If we say that an item is gold, we guarantee it to be gold. If we say it is a Rolex, we guarantee it to be a Rolex. If we say it is a diamond we guarantee it to be a diamond. But we do not guarantee grades or values of items. We do our best to give a fair and accurate description of each and every item listed. No grades of condition, authentication of signatures (unless witnessed by Silver Leaf Auction Company) on sportscards, memorabilia items and autographs will NOT be guaranteed, regardless of authenticator. Silver Leaf Auction Company does their best to describe all items, but in no way are they to be considered experts in grading or authenticating signatures or conditions!
