Values listed on this site are based on estimates which are obtained from various sources. The values often vary from prices achieved in actual transactions, especially for thinly traded products. The values are estimates only and are not firm bids or offers. The values assume no unusual market conditions and are generally for small quantities. The values do not include any dealer mark-up, mark-down or commission and, therefore, may be different than the price you may actually receive in the market. The estimated values provided are believed to be reliable however the accuracy cannot be guaranteed.
