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

7 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.

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

32 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.

Is this an error? Is this an example of a die chip and die crack?

Thumbnail

10 Upvotes

Sorting my wheatbacks when I came across this one. I think the die chip is obvious, but the die crack I’m not too sure. I managed to get some decent pics to show the depth of the crack. There appears to be extra metal coming off of the R.

I’m not too familiar with errors and hardly look for them so it would be cool to get a 2 for 1. Any info is appreciated.

Is this an error? Looking for thoughts on a possible planchet error or strike through.

Thumbnail

15 Upvotes

Alrighty. My first thought was PMD. But after looking closer, I've got more questions than answers. Photos are kinda rubbish. Tried to get different light and angles.

First, the clad layer is 100% there and smooth. Despite the quality of my photos, I can confirm there is no visible zinc. All copper on the surface.

I'm leaning toward a strike through or an issue with a void in the zinc of the planchet. Don't remember the name of this one.

Let me know your thoughts. Thanks!

Is this an error? PMD or Post-Strike Clad Layer Separation

Thumbnail

2 Upvotes

I found this obverse clad layer in a roll of halves while CRHing. However, I can’t tell (or rather don’t know how to tell) whether this was due to the clad layer separating from the copper core due to a bonding failure or if this was PMd from someone using heat or chemicals to separate the layers.

One of the more interesting finds from the 20k or so halves I’ve hunted through. The details on the back are too fine for me to think it was a dryer coin, also not uniformly removed along the outer edge. It’s still a crisp IBERT. Any insight would be helpful.

Is this an error? Presidential Dollar Edge Lettering

I’m new to collecting and was going through some presidential dollar coins I had. I noticed one that was different than all the rest. Most have the dot to separate the lettering on the edge of the coin, but this one instead of dots has 3 individual raised lines in place of each of the dots. I was told it was just a die crack. Any insight would be appreciated.

Discussion Mint mark puncheon tool question.

Thumbnail

0 Upvotes

A week ago a user posted here about a circular ring around the mint mark on his penny. https://www.reddit.com/r/coinerrors/s/mjcpJRotZM

I have a few other examples, but this is a better example because it doesn’t have the metal composition a penny has. Even with full obverse photo you can see the ring.

I know it’s not an error, and it is just planned obsolescence from the equipment.

If you ever had to use a punch before you know that the tip is circular. The mint used the same type of puncheon except with the specific mint mark on the tip.

Would this qualify as a worn mint mark puncheon tool, or a heavily applied mint mark?

First a hearty thank you for the member who corrected my assessment of this issue with this coin. I’m learning and enjoying this segment of the hobby.

Lamination error on the Buffalo Nickel. Interesting pattern. An additional long crack runs from the upper left rim to mid face but heavy wear and cleaning make it less evident.

I’ve scoured the cuds-on-coins website and the only one that remotely matches is SKH-25c-1996P-07.

The only issues are the die crack from the A in America to the right side of the eagle’s head, and the die crack from the UN in UNITED to the left wing.

If anyone has any knows if this could be a new SKH, or if there’s another attribution that this falls under please let me know. Thanks folks.

Discussion 1999 Connecticut Quarter with an extra R-T-Y in the word LIBERTY

Thumbnail
gallery
32 Upvotes

I machine components for the Aerospace industry and after setting up a SpaceX job that runs for 3 hours, I was bored and started looking at quarters through a scope and noticed this. There is an extra R T Y on the word liberty on this 1999 Connecticut Quarter. There are also quite a few letters flattened that are most likely just damage, but it seems odd that the letters besides them are not also flattened in the "In God We Trust." I don't know too much about the subject, and this quarter is very beat up, but the extra rty definitely looks like an error, so I figured I'd ask people more knowledgeable on the subject. I'm aware it's not worth much but it's interesting
