Ahwash lists this variety as a business stike and describes as "completely upset, 180 degree rotated caused by misaligned dies". However, the plate coin to the left is certified by PCGS as a proof. There are ongoing questions by variety specialists as to the originals of RRDM for this important and unappreciated variety. Was this event a minting error or were the few known specimens struck as patterns with "medal turn" die alignment? |
