In general. I've been using the internet to help identify some of the more famous ones, like double die, large/small date, wide/close AM, etc. However, the newer coins don't have commonly known errors yet. What should I keep an eye out for? Mainly I'm looking for general guidelines on just the variations that could be worth money.

You should probably look to the standard references - Strike it Rich or the Cherry Pickers guides.
If you really want cutting edge, then start with CONECA and go from there.

The list is too long to elaborate on here. BStrauss3 gave some good advice.

I am assuming that you mean pennies. You don't mention if your going to open bank penny boxes, or going to purchase rolls of specific years to hunt through. I suggest going to http://www.pcgs.com then go to the COIN PRICES tab and then look for say MEMORIAL cents. Look for the years that show doubled die, OR.... look for any year that has a PLUS sign in the far left column. Those can be pulled down and expanded. For example, if you go to the 1972 year and open up that "PLUS" sign, it will list the doubled dies types and years. Some may show examples. You will see RPM's DDO's DDR's and other examples there. Its tough to say if there are particular years or a spread of years to search. I typically try to concentrate on 1955 to 1980, since most of those are copper and probably will not ROT over time. I am not a fan of Zincolns...... zinc pennies. Edited by Collector-Corner

One other thing. I use a microscope to look over these coins. I used to use a Loupe but the eye stain is too much for me. If you want to see things up close with clarity, and can afford about 100-150 bucks, the AmScope have a few STEREO MICROSCOPES that work just fine. You will NOT need anything over 60x multiplication, typically 5-30x is plenty...with an occasional 40x once in a blue moon. |

In terms of value, off metal strike errors have got to be right up there.
For instance, an Australian Florin, struck on a U.S. wartime nickel blank. Error kindly produced by the SF Mint, in fulfillment of a contact to produce Australian coinage.

(MisAlignedDie) The happen when the hammer die (adjustable) is not aligned with the anvil die (stationary). The one side of the coin will be noticed to be slightly off center. These are common, but when the devices fall over the edge of the hammer dies strike, then they are collectable. Common one:   The devices are very close, but not over the devices. Collectable ones: Note the devices over the rim and the weakness on the reverse letters   Sorry to hi-jack the thread, but wanted to answer a sub-question.Edited by coop

I've found examples like that with the thicker rim in the 1997-99 era. You could feel the difference when holding them. But they are normal weight. The setup just made the rim thicker.

What does it mean to have a 2.8 gram penny? 1982.

3.11 is normal for a copper planchet.
Zinc is lighter. 2.5 grams.

I just got a new magnifying glass, so I was thinking of looking at some of my old pennies again. Would I have higher chances of getting interesting finds from pre 82 or post 82 LMC's? |

Depends on what is in them. 1972 is a great year. 1995, 2006 and 2002, 2004, 2011, 2012, also has some good ones. I look through all of them.
