What is the lowest MS grade assigned to a coin that has gone straight from the mint, to the initial

.......... without having sustained any post mint damage?
Is there any MS grade(s) that will not be applied by a TPG to a coin that has no post mint damage (i.e. MS 60) regardless of how lousy the quality of the coin is (i.e. a branch mint Lincoln cent or Buffalo nickel from the 1920's struck from worn out dies or a 1969 P quarter struck from a lousy planchet from worn out dies)?

I guess a definition of post mint damage would be in order.
#1. It could be a coin that has not been damaged at all after it left the mint, even though while at the mint is got beat up (dings and marks) after striking and before leaving the mint by being dumped into a bin with other coins, being spilled on the production room floor and stepped on, being dumped into a bag that was then tossed onto a pallet.
#2. It could also mean a coin that remains in the same condition it was in the moment it left the striking chamber.
For the purpose of my question, I will use definition #2.
