Beginning A Search Of 8 Rolls Of 2014 LSC.

As a newbie I think this is a good question and wondered that myself, how fast seasoned pros can go through a roll of coins.

I'd say 20-30 seconds tops to decide whether a coin should be set aside for further review.

Modern coins single squeeze doubled dies for the most part are so subtle that they rarely garner any attention. (Exception being the 1995) But searching new cents does give you the best chance at finding a discovery piece. Although I prefer searching pre 1973 solid date BU rolls.

An 10x magnifier an an eye catch differences. First step. Then depending for what you look more or less time.

@Early. You can catch fast those, no doubt. Nobody can replace years and experience with some photos or articles. BUT: In one month I will finish the study of the design varieties on Kennedy halves (my most love design), and give to you to see. I bet will take more then 30 min. (I joke) I will send you the studies, me or Miguel.

I think that this is a good question but in my opinion, there are a lot of factors. Some depend on the person in general, your comfort level with the type of coin you are presently searching, how you search and your level of knowledge, for all you are searching.

Going back to my very first factor, I think different folks pick up on different things, at different paces and depending on who is guiding you, that can also vary. I occasionally search BU rolls but for the most part, search bank rolls, which I think will teach you more and are more cost effective than any other type of searching. Many of my mentor's search only BU coins or pick auctions but I have not reached that level yet and still really love searching bank rolls, have done it for years, don't know if that will ever change for me.

Back to your original question, as for time on each coin, I know folks that use loupes and spend about 4 seconds per coin, that's both sides. I tried the loupe and cannot do it. I search with a scope on my laptop and take about the same time levelsofmadnes does. I search varieties, clashes, trail dies and anything else that stands out. As time goes on, you will recognize many of these without even thinking about it.

At the end of the day, when you have searched a roll or several and are not comfortable with what you have done and the time you have taken doing it, go back and do it again. In my opinion, it's a comfort level that you are happy with and that may change, from time to time. Have fun doing it though, or quit.

For a modern BU roll most of the doubled dies will be pretty subtle. For 2014 you have DDO-001 which you likely won't miss, and DDO-003 that has a die chip in the 4 so again, knowing to look for that you won't miss it. All the others are pretty light. So, best way to see the extra thickness is to look at them quickly one after another and note any that seem off. For this I just set them all out, five rows of ten coins, and scan then with a loupe (note I use a headlamp as a light source so no need to pick up the coins one by one as the light moves as I move). Once set out it takes maybe 90 seconds to scan them all, unless of course odd stuff is showing up. For 2014 you just look at the RTY and date for thickness, then a quick whirl of the loupe over the rest of the coin to see any trail dies or other stuff. It's fast, and I doubt I miss much since looking at one set of RTY after another is a great way to notice when one is thicker than the others.

Any longer than that, you will find Machine Doubling, and will waste more time with that.

1. Machine Doubling will be on the outside/inside edges of devices.

2. DDD that will be on the fields (not on the devices) towards the closest rims.
