That's Die Deterioration Doubling unfortunately on the mint mark, caused by a worn die issue. It's not an RPM. RPM's are no longer possible, since they stopped punching them by hand in 1990 (1989 was the last and final year for Business Strikes. They also stopped punching mint marks by hand for proof coins in 1985). https://en.numista.com/forum/topic60172.html http://www.error-ref.com/die-deteri...on-doubling/
