Die clash marks around the lips come from the wreath on the reverse. It usually takes a letter transfer from the word LIBERTY, the mint mark or the M of the designer, even the D from DOLLAR or any other letter for the
VAM to get a subletter such as A,B,C, etc. Mark Kimpton told me that he thinks 25% of the Morgans are clashed but that only 10% of those have the letter transfer. Hope this helps.
