Another factor I forgot to mention is the dates of your coins are not fully known. Comparing different years must take in differences of master dies used and any changes made, such as the mintmarks...these were placed onto the working dies individually by hand until 1990, when they became hubbed in to the master dies basically eliminating the RPM errors. Small changes may have been made on other details from year to year, die to die as well. Take the FG in 88/89 with and without cross serif in G. Some were minor ,others major.
