First Attempt At Roll Searching

I've read that it is not so common, but I'm averaging between 18-22 per box. My bank in NJ is getting their roles from N.F. String & Sons from Harrisburg PA. The boxes so far have been good. Their nickel roles have also been good. I'm going to keep buying roles from them because their supplier seems to be giving out good stuff. My bank does not however, have half-dollar roles. I'm trying to convince them to order for me. I'm also trying to get them to let me look into their Coinstar/whatever brand coin machine because it does collect halves.
Any good advice on how to approach your branch to have you look through/buy the bags from the machine?

Searched a box of pennies today, netting 15 wheaties. Found a 1955 poor mans DD(well, it's not really a DD_), and a 1944S. The 44S is not valuable, but I'm happy to find any of the older S coins as those are the ones which are missing in the cents album I'm making for my older boy. Those S cents seem hard to come by on the east Coast.
Also found a few Canadians, one from Panama and one from Barbados.

No problem to beg, and I understand that about every bag I would get will be short so I wouldn't complain about that and I also wouldn't dump them back on the same bank; I can split between two. I have pretty good relations with my main bank, so I'll pop the question.
I assume you are buying full bags, correct?
Also, if the bank is not used to selling bags, how do they technically sell you the bag? Are there any internal issues they face like the coin machine count, selling a bag, etc..? Is it a simple transaction for them where the machine count doesn't matter and they can sell what they want?

Sjh, I would not recommend dumping ANY of the coin youve bought back at the same bank, if you meant splitting dump between the buy bank and another branch. I don't even dump at a different branch of same bank, as word gets around between them.

Got through box 1 of 2 of Lincolns:
- 21 wheaties.
- Oldest found 1910. Also found a 1918 but already found this date last week.
- Two from the 30's, including a 1937 that looks like it was once dipped in gold.
- 7 from the 40's.
- 10 from the 50's, with a semi-red 52 S.

Searched a box of pennies tonight, and a good box it was. 43 wheaties:
-1917
-1920,29S
-1934,34D,35x2,37,38x2
-1940,41,42x2,44x2,45,46,48,49
-1950,50D,51D,52,53,53D,55x4,55D,56x5,56D,57,57Dx4,58

One of the 1955's has a clear doubled 5 in the last 5 of the 1955.

I usually pull 18-22 wheaties a box, so this was good for me.

Pulled a few red 1960's coins too.

14 Canadians, with the oldest being 1951.

It all depends on the reasons for doing coin roll hunting.
I do focus more on the pennies and nickels because I am collecting. I'm building two sets each for my boys from the coins that I find. I also fill plastic coin tubes with 50 cents of each year/mintmark for pennies, and also started tubes for the nickels.
I also look for those elusive semi-rare or rare dates.
CRH is a part of my coin collecting hobby. I do collect/buy at shops and shows for the four main coin denominations that I am currently focusing on. CRH is however fun and inexpensive.
Maybe someday you can get a cheap folder or two, and give those coins that you find a nice home.

Haven't posted any searched box results lately. Found a bunch of wheaties over the last 2 or so weeks, but nothing of consequence.
Searched a box of pennies today. 14 wheaties with the earliest being 1936. Also found a 1946 & 1958D red/brown. Also pulled 7 red or red/brown cents from the 60's.
Found 12 Canadians with the oldest being 1951.
I did have an unusual find. Found a 1933 English 50% silver six-pence piece in a penny roll. Silver in a penny role? Go figure.
