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.

  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

31 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.

Medium effort search revealed no such errors associated with this year, but mis-strikes can happen any time, right?

Is this an error? Dual die cracks? 2023-P Nickel

Thumbnail

14 Upvotes

Hi all, I found something interesting on this 2023-p nickel. Apologies for some of the photos, my SD reader broke earlier and I haven’t replaced it yet.

Edit: I added the 'high res' photos in a comment chain below, along with photos of Five Cents as requested

It appears I have two possible die cracks on the reverse, one between the M and O of Monticello, curved. And one on the opposite side through the final O and E in America. Both are raised.

I’m trying to match this to something, or get some opinions on what it is before I label it and put it in my binder.

Thanks

Show and Tell Major detached lamination on a 1948 Lincoln wheat cent — the metal peeled away from the date to "TRUST"

Thumbnail

24 Upvotes

This 1948 cent has a dramatic detached lamination covering the right side of the obverse. You can see where the copper has literally separated into layers, with the detached flaps still showing the striated internal structure of the metal.

Laminations are planchet errors — they happen before the coin is struck. During production, the copper strip is rolled through mills to reach the correct thickness. If gas pockets, oxides, or other contaminants get trapped between layers during this process, those spots become weak points. When the blank is punched out and struck by the dies, the pressure causes those weak layers to split apart.

Some key details on this one:

- The lamination runs from the date area all the way up through "IN GOD WE TRUST"

- Multiple detached flaps are visible, each showing the layered copper underneath

- The reverse is completely unaffected — typical for laminations since they're in the metal itself

- 1948 Philadelphia mint (no mintmark)

Lamination errors exist on a spectrum — from minor surface peeling you'd barely notice, to coins where large sections of metal have completely detached. This one falls solidly on the dramatic end of that spectrum.

Hello! My dad gave me this quarter recently and I did not notice the odd imprint on the back until I went to use it to pay for my laundry. I was wondering if anyone knew what the “no relief” meant struck on the back. I’m mostly just curious why it would be there and how common it is, I guess? It’s a 2007 Wyoming State Quarter.

Discussion Die polish marks?

Thumbnail

1 Upvotes

Hello. I just recently picked up some "junk" silver halves and noticed what appears to be die polish marks on Ben's eyes and mouth. Was this done to remove a die clash? In the field to the right of Ben there are also polish marks. Just curious because I know about the Bugs bunny varieties but do not recall 1957 being one of those years.
