Questions For You About Rim Dings And Market Acceptibility

I now have two coins in my collection with small rim dings and PCGS straight grades. I examined both coins before I bought them, liking the faces and looks of the coins before commiting to them (buying the coins, not the holders), but I am wondering what you all think of these rim dings and how they affected the grading. I have shared both of these coins in the past--one years ago (a 1908 St. Gaudens Double Eagle which graded MS-63) and one last week (an 1849 Coronet Eagle which PCGS called MS-62). The 1908 St Gaudens rim ding is at about 6:30 on the obverse. The 1849 Eagle's rim ding is at about 12:15 on the obverse. It seems the rim descends on to the dentils. I'm not even sure if it's a "rim ding" to be honest.

Question 1: Would you prefer coins with more contact marks on the surface, or these which both seem at least quite strong for their grades?

Question 2: Is the policy to "net grade" coins with rim dings that are not so offensive/abrasive, and that could be attributed to bag mark damage?

Question 3: On the 1849 Eagle, is it even a rim ding? Or was this a striking issue from a failing die that the mint polished aggressively?

Note: the 1849 Eagle's rim is WAY harder to photograph, given that the area hides behind the plastic bit that holds the top of the coin in place. Here's the important part--this "rim ding" isn't on the edge of the coin itself--it's only on the coin's surface, tucked against the rim.

Here's my hunch--the 1908 St. Gauden's coin should grade MS(65), but the rim ding brought it down to MS(63). The 1849 Eagle I am way less sure about, as it's much less noticeable, other than looking like a tiny dark spot just past 12 o'clock. Do you think the 1849 Eagle would have had a shot at MS(62)+ or MS(63) without the rim ding?
