Sometimes the die pressure of the subsequent striking of the coin obliterated the marks, and sometimes they can still be seen, either faintly, or as in the case above, more noticeably.  Like some eye appeal issues such as dark or uneven toning or things like that, adjustment marks are considered to be a minor detraction, but they aren't really a "problem",  since they were done by the mint prior to the striking of the coin. This is why the coin above straight-graded. In my experience, this is most often seen on 18th century coins, which of course the little half-escudo above is.[/QUOTE]
