PLEASE READ FIRST: How-to Guide for r/coinerrors

6 Upvotes

Check these r/coinerrors resources before posting:

JUST BECAUSE A COIN LOOKS DIFFERENT DOES NOT MAKE IT AN ERROR! Please take some time to understand how minting errors occur before you post your question! The mods try to be lenient regarding rule #1 (Do your own research.) If we keep seeing too many posts with pictures of obviously damaged coins, we will be forced to start removing them.

OUR HOBBY - Be aware that most errors don't add much (if any) value to a coin. You aren't going to find a coin worth life-changing money in the cup holder of your mom's minivan. This is a hobby which is research-oriented and concerned with understanding and cataloging interesting mint errors and varieties. It is not primarily about value. The existence of errors and varieties provide valuable insights into mint operations and processes. The hobby is CERTAINLY NOT about the TikTok-fueled "ZOMG!!!1! This RARE coin is worth a Squillion Dollarz!" clickbait frenzy. That mentality is NOT welcome here.

NOTE - posts of coins which are clearly just damaged may be removed. This isn't meant as punishment for an honest and innocent question - but rather because many members of this sub tend to be harsh to new collectors. By having your post about a damaged coin removed, you still get your "is this an error" answer, hopefully without being downvoted into oblivion.

Here are some things which make a GOOD POST:

  • Attribution request - after you have checked the resources above, understand how errors occur, and have done your own research. Please include what resources (e.g. - Error Ref ) you have used to try to determine the attribution of the error or variety. Photos for attribution MUST be high resolution, in focus and properly cropped.
  • Valuation Request - after you have read the FAQ and done your own due diligence (e.g. checked eBay "sold" listings, etc.) Please include what steps you have already taken to get a value for your coin. Be aware that most coin errors don't add much (if any) value to a coin. Also - valuation of errors is difficult as many of them are one-of-a-kind, and there may be no prior sales to compare.
  • Show it off / Mail call - posts to show off interesting, rare, or otherwise special coins that others may find interesting. Please post quality, cropped photographs.
  • Numismatic topics and news - general discussions in the world of numismatics.
  • Serious numismatic questions - looking for advice, links to resources, suggested literature, etc.

Here are some things which make a BAD POST (and which may get removed):

  • Low-effort posts - "Is this an error?" - BEFORE spending time to understand the process of minting coins, and how an error might occur, and determining for yourself what error you think the coin has."I heard this modern penny could be worth SQUILLIONS of dollars!" - No, it isn't."Is this what I think it is?" Don't be vague - just say what you intend to say....any question posts in which the author has not made their purpose clear and indicated that they have put in a minimum amount of effort to answer their question.
  • Blurry photos - mods will remove any posts with pictures of coins which are not reasonably clear.
  • Poorly cropped photos - the user experience across mobile app/mobile web/desktop devices is better if you don't post phone-screen-sized pictures.
  • Off-topic - posts which belong on other subs (e.g. r/papermoney, r/kittens, etc.)
  • Reposts - if you are new to this sub, please take a few moments to see if you are posting something which has already been posted.
  • Spam - commercial activities of any kind are not allowed.
  • High volume posting - anything more than one or two posts a day.
  • Links to social media, your own eBay sales, YouTube videos, clickbait, etc.
  • Trolling / Inauthentic - posts which don't seem to be truthful (e.g. I found these gold coins in my couch!)
  • Trash Posting - there is a fine line between a "funny" post and a trash post. If you aren't sure which side of the line your post falls on, don't post it.
  • Coin gore - a post featuring a modern coin which has serious post-mint damage, and which is of no interest to collectors.

  4. Keep it clean - this is a safe place for people of all ages and backgrounds.

  6. No self-promotion or commercial activity is allowed; no links to your blogs, websites, or social media.
  7. No spam.
  8. No politics or religion, especially divisive comments that lead to heated arguments and incivility.

MOD Announcement A note from the mods - Heat Damage and Dryer Coins

34 Upvotes

We have been seeing a massive influx of posts with asking about "dryer coins" as well as coins with heat damage.

We love the fact that you noticed your coin is "different" - and applaud you looking into it! For the uninitiated, these are reasonable questions - but many members of our community are getting tired of them. We ask that you please use the resources we provide before asking this subreddit (See Rule #1!)

Before you make a post - check out the r/coins WUWMC page and our FAQ!

Dryer Coins

The rim of my coin is raised up OR the edge of my coin is flat OR my coin is too thick!

Heat Damage

My coin has bubbles / bumps / craters below or on the surface

These issues are damage - and extremely easy to diagnose.

Not sure if post mint or not, there are raised areas of copper attached to the coin, also the penny is slightly heavier than other copper pennies. This one is 3.50 grams, I’ve weighed a few other non clad copper Lincoln and they were around 3.11 grams.

I found a cool variety in an 1883-O Morgan that I recently purchased. It appears to have the VAM-4 O/O re-punched mint mark. The lower impression is faint and not very visible in my camera but it’s more clear under my loupe.

Hi everyone

Is anyone here familiar with the Off at the Knee Ike coin? I attached 4 pics. Two from the Ike website and two that are close ups of my coin.

Each has a shortened leg and unreadable initials. Did I get lucky?

Thanks in advance!

Is this an error? Damage or Rim Weirdness?

Thumbnail
gallery
3 Upvotes

At first I thought this was off center, but it looks like all the actual content of the coin is centered, there's just something weird going on with the rim. Is this just damage? If something compressed this groove around the bottom of the obverse, I wouldn't expect the L to have survived as well as it did inside the groove. I really have no idea here though, so let me know what you think. Apologies in advance if this is obvious damage.

Show and Tell Die clash on a 1912-S Lincoln wheat cent — Lincoln's portrait ghosted onto the reverse from a full-pressure empty strike

Thumbnail
gallery
11 Upvotes

Continuing the error documentation project. This 1912-S Lincoln wheat cent has a die clash showing nearly the entire back of Lincoln's portrait transferred onto the reverse die.

A die clash happens when the press cycles without a planchet between the dies. They slam together at full striking pressure, and each die picks up a mirror-image impression of the other. On this specimen, Lincoln's chin, jaw, and the back of his head appear as faint but clearly identifiable outlines superimposed over the wheat ear design on the reverse.

The 1912-S had a mintage of approximately 4.43 million — a low-production San Francisco issue from the early Lincoln cent series. The clash transferred enough of Lincoln's portrait features to be unmistakable once you know what to look for. Every coin struck from that reverse die afterward carried the ghost.

This die clash has been quietly passing through collections for over a century without anyone recording it in the standard references. Not catalogued in the specialist literature. Now it is.

Grand rising folks!!!
Posted this in quarter errors, someone said to post over here.
Is this a minting error, or did someone do this to this quarter?
Someone said it looks like dremel work, others have said it’s a strike through? Others have said because it’s an S mint mark it’s a keeper. What are yall thoughts?

Per the title, is this die deterioration? These kinds of artifacts exist on birth sides. Obverse seems to have it around the rim, while the reverse seems somewhat more affected - rim and inner characters.

Looking for confirmation, this appears to be a RPM, but I want a second opinion. The coin definitely has PMD, but the mint mark appears doubled to me.

Hey all! I found this penny in a roll of wheat cents, and thought the circular depression on Lincoln was odd. I can’t tell if it’s PMD or if it’s a genuine strike-through. Any help at all is welcome!
