I see two coins with same Mint mark style with the bulb end and blunt end numerals.
They are the correct MM,s
I looked up the MM style for that year
And RPM AND
DDOThe other coin has sharp numbers and serif block end and serif is split and shows a
DDO BUT can't tell if s over s s over inverted s because it looks like a 8 at times and depending on how I positioned my phone it also looks like s over d because from what I found that MMS-008 the tall Mm on the 2 are correct the double punch MMS-009 she shown on the other 68 wasn't used or supposed to be used until 1974 so it's somebody to shed some light I would appreciate it
