Common Errors Found In Circulation

Coins | 1943penny

Hey Guys! This is my first article to be published in the ErrorScope and I hope it is not the last. Today I wanted to talk about common errors that can be found in circulation. Some of these examples will be more expensive than others and some will be more scarce but all of these have some things in common, and that is, they are all errors that can be found in circulation. Some errors that are in these publications are clipped planchets, wrong planchets, off-center strikes, and a bunch of others that are easily noticeable and can be spotted and picked out by even non-collectors. Thus making it nearly impossible for finding those in a roll of coins. So, without further ado, let's get started!

The most common and my personal favorite error are doubled dies! Doubled dies can be very valuable as it could be $200,000 or as little as a single dollar. They can have very minor doubles or very major doubles. Doubled dies are created when the hub strikes an additional, misaligned design onto the die. There are many ways this can happen which have been classified into eight different classes by me. See how it works, it’s pretty cool.

Class 1: Rotated

This happens when the die receives an additional rubbing that is misaligned in a clockwise or counterclockwise direction.

Class 2: Distorted

This happens when the hub’s design moves to the rim between rubbing

Class 3: Design

This occurs when a hub bearing a different design stamps a die bearing a different design

Class 4: Offset

This happens when the die receives an additional rubbing that is misaligned in an offset direction.

Class 5: Pivoted

This takes place when the die receives an additional rubbing that was misaligned via rotation with a pivot point near the rim.

Class 6: Distended

This occurs when the die receives an additional rubbing from a hub that was distended.

Class 7: Modified

This happens when the hub is modified between the die's rubbings

Class 8: Tilted

This happens when a die and/or hub is tilted during a rubbing.

Here are some examples of double dies;

The second error I am going to be talking about is pre-punched mintmarks (RPMs). These are quite common and usually don’t reach prices over $10. RPMs occur when the letter punch that is used to punch the mintmark into the working die leaves two or more offset impressions. The impressions almost always overlap. The only situation was an RPM would exceed a value of $10 is when the mintmarks are totally separate from each other. In those cases, they would be considered a rarity and might reach a price of $5,000. The second mintmark is usually thinner and smaller than the normal mintmark. This is due to the fact that the apex of the raised letter on the letter punch is narrower than the base. In other words, the raised letter on the letter punch tapers in vertical cross-section. The era of RPMs ceased in 1989 when the U. S. Mint began placing the mint mark on the master die instead of punching the mintmark into the working die. The majority of RPMs are found on either San Francisco or Denver Coins. But RPMs can also be found on coins from Philadelphia, Carson City, New Orleans, and others.

The third and final error that I am going to talk about is Missing design elements or sometimes known as “Other Omitted Design Elements”. Missing design elements are coins that are missing a part of the design that is found on regular coins. Some very well known examples of these coins include the 1922 no “D” (see above) cent, the 1968 no “S” dime, and the Missing Branch Cent. I have included pictures below. These coins can reach exceptionally high prices of over $9,000 and usually, the lowest you might see them at is around 200-400 dollars. So overall this coin is one that can be found in circulation if you have a good eye and one that can reach high prices as well! This would be a great coin to add to your collection!

Thanks for reading,

I have a couple of classic coins that have double die characteristics. The first is an 1853 Arrows and Rays half-dollar. The second is an 1858 Large Letters Flying Eagle Cent. I also have an 1851 large cent with evidence of a grease strike through. Errors are an interesting part of numismatics.

While I don't seek them out for my collection, searching through pocket change and finding them is a blast. Those which I've found end up in flips and tossed into a box. After reading your blog I believe it's time to buy a Dansco with blank pages and begin fill it with the variety labeled accordingly below. Thanks for motivating me towards a separate collection.

I just started doing the exact same thing after I wrote this. I guess it motivated me too!

The different classes of doubled dies have always eluded me, but this article helped me understand them better. If you want to send it to CONECA, make sure that you send it to the right person, check the CONECA magazines, they tell you where to send. I wish you the best of luck on your quest!

Very informative. I learned quite a bit from this, as I am not an error collector, but will certainly search for them. I did find a quarter on a nickel planket. Thanks

Errors are always an interesting subject and the type of item you can still find if you scan your change carefully. Congratulation on your Errorscope article, that is quite an accomplishment.

Great blog. This is what we look for in coin rolling. We usually don't care how it happened but we're happy when it does. These I know about I have had a few. Thanks for your research and sharing it with us. Keep it up.


Level 6

Try again with the pictures. This is a very good blog. Well researched and explained. Congratulations on being published. Error coins are very cool.
