What is the value of an 1897 US 10 cent coin?

As of 9/8/2011 Most silver 10/25/50 cent coins and dollar coins(minted 1964 and earlier) are worth more now for their metal content (90 % silver) with silver at $40 p/ounce ++. Rough guage today is coin value times 29 or, for dime, value is $2.90 with silver at $42 p/ounce. Use 40% of that figure(40% of $29) for Kennedy halves dated 1965-1970 since they contain 40% silver. xman
