Lincoln Cent Roll Hunters Guide?

Joe: There is even more for your list. RPMs and Overdates (On 19 century coins) which are other varieties to search for. For varieties this site helps you to find the different types of Cent varieties.

On the search page you can type in Date/Mint mark/type of variety and see what happened with listed of known varieties. There are a lot more than the ones listed also to consider. So study what types of varieties are found and consider this on all years as you never know what else hasn't been found.
IE:
I knew of a doubled die for 2004 that showed doubling on the EPU (E Pluribus UNUM)

With that happening on a few different dies for this year, I started looking for the same doubling on all other years of Memorial Cents. Guess what I found?

This was new variety that I found. So far two are known for this date. The doubling looks better with a closer view:

Unlike Machine Doubling, it is a true doubled die. On Machine Doubling the devices are struck, then damage before ejection. These are very common and worth what they say on the back on the coin. But The doubling that is valuable is when the doubling is on the die. Thus the term: "DoubleD die." (The capital on the Last D is not an error, but to enhance a proper term that some may overlook.)
Looking forward to your finds. I usually get a box when I can from the bank or when I go out of town when traveling. That way you get some different rolls to check. Less time going back to the bank repeatedly unless you need to go back several times. So when searching, anything that looks different set aside for a closer look. Read posts. Do searching on coppercoins.com Just take advantage of free information on the sites and train your eye what to see differently. When you don't know about something, ask! All here will be glad to help or add to your training. Save anything out of the norm. I even save BU looking Cents that are several years old (2000-PRE) just so if something new is found, at least you can re-check your better coins. If there is a new find, what is better than having one on a better coin. Also you may start your books and up grade when you find a better example in circulation. Hope this helps.

Here's the scoop...

Following ANY comprehensive listing and only looking for what's in the list completely negates any chance that you could discover something that we do not yet know about. A couple of years ago a 1982 small date doubled die reverse was discovered that changed the die variety world, and there had NEVER been any kind of doubled die known for small date 1982 cents. It went over 25 years without being discovered.

DO NOT use lists to search by. Learn what a normal coin looks like, and pull out anything that looks different. Study websites like mine for the characteristics to look for, sort your coins by date, and look for anything odd. You will eventually catch on and will be able to spot the die varieties and errors without a problem.
