You can try any coin dealers near your place, or I can help you with its valuation. The 1897 silver Morgan Dollar has a value of $20 to $25 in grade average circulated with moderate wear on entire coin(all mints), up to $27 to $30 in nice circulated(all mints), and between $30 and $45(mintmark S and no mintmark) or from $150 to $350(mintmark O) for near uncirculated grade. The mintmark is located under the tail feathers of the egle on reverse of coin.
