Good points, Mr. Spivey. If memory serves, you said you and the original owner of the coin, an OG-MC peer at the time on the shared playground knew the fifty-cent coin was his. So, why was it necessary to create a fictional "reality", so to speak?
Just in my experience requesting school records for my First person historical record I was plesantly surprised at how meticulously Cook County, IL, and CPS ( Chicago Public Schools) recorded and kept my birth and educational records. I would like to positively stereotype the dominant Midwestern German Immigrants as being equally thorough and detailed in Minnesota. They were posting newly certificated teacher profiles for public viewing when I first became licensed by St. PAUL Public Schools back in '93-'94. Good luck on your search.
