Currently, on
ebay, there is a bid for $10 for two rolls of my early Wheat cents (1910 - 35) in VG - F condition...that's $5/roll or ten cents a coin. Previously, I've sold later Wheats for up to $3/roll (or six cents a coin). I have sold rolls of one date (later Wheats) for around two dollars a roll.
So, there is some demand for one-date rolls. That demand does not guarantee a good price. And costs associated with selling on
ebay can greatly eat into the profit margin.
I'll say this: you'll get substantially more for your rolls of 30's than your 40's and marginally more for your 40's than your 50's.
For example: "good" condition coins:
early 30's coins, not including key/semi-key dates, can have a value between 15 and 100 cents.
later 30's coins, not including key/semi-key dates, can have an average value of 15 cents/coin.
1940's coins have an average value of about 5 - 6 cents
1950's coins have an average value of about 5 cents.
So, given that hypothesis and information, the cost of selling and shipping them can diminish your returns greatly, as the coins' dates get more recent.
The "condition" or grade of the coins is a very important factor, too.

I hope this information is useful and/or answers some or all of your questions.
