That mark you might be seeing is the designer of the obverse, Gilroy Roberts, and that is his monogram. In the vast majority of the time, this area would not warrant any premium value. And of course, that 1973 is a common clad coin; you would have to find the ones before 1971 to get 40% silver, and before 1965 for 90% silver.
