Ahhh, you missed the main part of the time savings by not knowing one little word. :-) "Ryedale". And amazing word!! Let me explain.
<<How can you watch TV and look at all those little numbers

I listen to TV while searching, but I have to stop searching to watch TV. I work a lot faster with the TV off.

>>
Nope. I watch the TV, and don't search at ALL. I just unwrap and dump in a penny box for later sorting. No time needed at all. Granted, I KNOW I'm a junkie, but nope, no need to look while unwrapping. The reason is below...
<< So you dump where you do your Business? How's that working out for you? >>
AMAZINGLY well. they talk to me, sometimes come over and help me dump, and whenever they open the bottom to change bags they let me keep all the foreign coins in the reject bin. They keep any silver they find for me (Their bank says if they change out a coin for another, or keep something that couuld got oa client they are fired. And these people con't CARE about coins, for some odd reason) We talk all the time, and they pet my puppy while I dump coins. (SHe is yong enough to be pet at this point. Soon it will not be allowed) When I miss a few days in a row, they give me greif about getting lazy and not working my pennies at night and not showing up. It is the oppostie of what I have heard about banks in almost every way.
<< I wish my bank had one that fast. can't speak for penny's but it takes about 10 minutes to do $2k in Halves at my dump sites. And I pray it don't jam or fill up. That probably never happens to you though....HUH.... LOL>> I did almost $500 in halves in less than 1 minute. When it doesn't fill. But, most of the time I fill the bags. And check this. Because I drop so many pennies, they made a change in the bags for me. They changed what 2 bags hold, so that they too hold pennies. Now, when I fill a bag or two, it changes to other bags and keeps going. They have SIX bags just for pennies, but only one now for nickels and dimes. They used to have 4 for pennies and 2 for nickels and dimes. That's how much they go out of their way to help me. :-)
<< Oh one other question. What is a
Ryedale? 
>>
Now the big answer. A Ryedale is a machine that seperates coins based on composition. Call it a sorter with a metal detector in it. I unwrap my pennies and throw them in a box as I go. Never look at them. Then, I spend time when I have it later in the evening or during the day putting them in the Ryedale machine. It separates the copper fromt eh zinc. I throw the coins in at top,. and they come out separated on two chutes below. It has one problem. The way it works is that it looks for copper and anything that is not copper goes to the "other" catagory. That means that older wheats and indian heads sometimes go to the zinc side. However that is NOT an issue, as I keep my eyes on the ZINC side when i use the machine. As the coins come out, about 50% of them show the back side. I cna see if they are wheats or memeorials. The other half? Most are shiny. SOme are darker, and I flip them with one hand as I watch for wheats. I have found a few older wheats this way, and think I may be missing one in a hundred, but for all the time savings I think it is well worth it. I get so many more coins because I go through more voume and if I miss one but gain 40 becasue I go through extra boxes I am well ahead.
SO, I watch the zinc side, pull out the wheats and IHs and then return the rest. When the copper side is full I pour it out and look more carefully for wheats there. That is where they are, of course. that takes me some time. But, i am only going through 16% of the total pennies, as that is about how many of them are copper here. I go through the pennies, and ALL of them are keepers. Either as coppper, or as wheats. I move them to storage and I'm done. :-)
There are spots to see the Ryedale in a video. I know it is on Youtube. I bet it is also at ryedale.com. Check it out, just ot SEE it work. It works fast, it works effecient, and it works pretty accurately.
And it allows me to watch tv while I unwrap pennies. :-)
