In Australia, we return our coins to the bank in clear plastic bags which the bank then weighs. We don't re-roll our coins.
The coins (by whatever mechanism), end up with a private company who re-roll them, e.g., Chubb, Armaguard. These companies then provide rolled coins to their customers. They also provide coins in sealed plastic bags. However I think those come directly from the Mint. Someone may wish to correct me.
So, in answer to your question, I believe it is possible to get MS from rolls, depending on how and by whom the rolls were 'rolled'.
The atached image is one of a number of coins that I found in one of my noodling forays. It looks better in hand, but I had at least 20 in the same sack of rolls that I would have classed as GEM/CHU/MS. I don't know how they came to be together, but they were better than what one would expect in a standard mint set.
As mentioned by neweden, Mint rolls will occassionally throw up a few MS, but in Australia we pay a premium for our mint rolls, and having opened a couple to find the majority are bag marked, never again.
Armaguard and Chubb have a contract with the RAM (I assume) to roll and deliver nationwide. I believe the US company is 'String'? These are simply bulk recently circulated coins. When I'm lucky enough to come across those rolls, I break open the Tail/Tails and search for Gems/MS. I usually keep the Head/Tails.
The beauty of opening rolls is that you never know what you'll find.

The following is a strikethrough ( Greaser as you call them) found in a roll that would have graded highly without the error.
