On a trip through Sacramento I stopped at a B&M and picked up a nice group of BU Lincoln rolls. All tubed, from late 40's through 58. The group included a small hoard of 20 rolls of 55-S. I love buying 55-S because they are generally nice quality with lots of varieties. What I usually do when I get a hoard like this is look through for varieties, and then sort them by approx grade. I sort in the order of Gem, Select, Average, and Junk. My criteria for Gems is to have no field marks on obverse and no major distracting marks, while Select and Average have more and more field marks of distracting marks. Junk have spots or fingerprints, etc.
Here's what an example roll looked like:

Out of the 20 rolls, one full roll had a small
Cud on the 9 of the date, a "Blob-9" variety. They look like this:

About a quarter roll had die chipouts on the 9, first 5, and the S and looked like this:

About a half roll had a partial BIE, really a B_E, of two varieties. They look like this:

And like this:

There was one lamination error that looked like this:

And one minor struck-through wire on the 9 of the date that looked like this:

There were 1-3/4 rolls of "Junk" coins, mostly ugly roll ends, fingerprinted or heavily spotted coins. Here's an example:

There were about 7-1/2 rolls of "Average" coins. Here is an "Average" Obverse:

And here is an "Average" Reverse:

There were 4 Rolls of "Select" coins. Here is a "Select" Obverse:

And here is a "Select" Reverse:

There were about 3/4 roll of "Gem" coins. Here is a "Gem" Obverse:

And here is a "Gem" Reverse:

Finally, there were about 2 full rolls of a mix of RPM #2, RPM #3, RPM #4, and RPM #5. Unfortunately no RPM #1 in the group. Also there were a few of the RPM South that I've pictured here before, and some minor RPM West. I'll take some high mag photos of some of these later and post the results.
Well, that's what I do with groups of rolls like this. It's always fun to look through a nice group of rolls and find some neat things in them!
