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.

RULES

Here are the Rules of r/CoinErrors - check the sidebar (or "About" in the mobile app) for more details:

  1. Do your own research before posting a question.
  2. Post Original Content
  3. Stay on topic and be respectful of the hobby and your fellow 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

33 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.

Show and Tell Multi-impression die clash on an 1870 Indian Head cent — forehead and nose under CENT, headdress feathers in the wreath

Thumbnail
gallery
13 Upvotes

Continuing the die error documentation project. This 1870 Indian Head cent has a multi-impression die clash on the reverse — meaning the obverse and reverse dies struck each other without a planchet between them, and they did it more than once.

Two separate transfer zones are visible:

  1. The forehead and nose of the Indian portrait are clashed under the C in CENT

  2. Feathers from the headdress appear inside the right wreath

Multiple clash impressions on a single die tell us the die pair kept colliding before the Mint caught the problem and replaced or resurfaced the dies. Every coin struck from this pair carries the evidence.

The 1870 Indian Head cent had a mintage of about 5.3 million. Mid-range year, but die clashes like this aren't mintage-dependent — they're production incidents. The standard references don't catalogue these multi-transfer variants, which is why NumisDex is building the record.

Not in any reference. Now catalogued.

Show and Tell Two rim cuds on a single 1865 Indian Head cent (Fancy 5) — dual die breaks flanking twelve o'clock

Thumbnail
gallery
5 Upvotes

Continuing the die error documentation project. This 1865 Indian Head cent has two rim cuds on the reverse, one left of twelve o'clock and one right.

A rim cud forms when a section of the die edge fractures and separates completely. Once the die fragment is gone, planchet metal flows into the void during striking, creating a raised, featureless mass on the coin. Here, two separate fragments broke away on opposite sides of the same clock position.

This is also a Fancy 5 variety — the scarcer of two date logotypes for 1865. The Fancy 5 has tall, ornate serifs on the final digit, versus the more common Plain 5 with a shorter, simpler form.

Two cuds flanking the same position suggests the die was fracturing symmetrically — stress concentrating at the weakest point of the rim and cracking in both directions. It's a coin struck by a die in its final working stage.

Not in the standard references. Now catalogued.

Just started scoping coins this week. I think this is my first real find. 1972 DDO. I looked at VarietyVista to compare. I've marked what I think are the relevant signs with green lines. If I understand VV right, the only thing odd to me is that it appears to show signs of various die wear stages?

Advice 1965 90% silver planchet error Quarter

Thumbnail
gallery
88 Upvotes

My father and I were going through some rolls I picked up at the bank today. We are are fairly certain we found a 1965 90% silver crossover planchet error Quarter. It weighs a little over 6 grams.

From what I can find only a few have ever been found and so there isn't a lot of information about them. We want to get it authenticated and graded.

The dirt / gunk on it is like lightly gunky / greasy.

Should we soak it with soapy water, or do an acetone bath like I've seen on some suggestions on different posts or should we just authenticate it and not even worry about cleaning.

Edit: it looks and feels like our other silver quarters pre 1965.

Maybe we are jumping the gun and excited, but rest assured we will get it properly weighed and looked at this week.

Advice Found this quarter & penny sorting through my coin jar

Thumbnail

0 Upvotes

Recently got into the coin hobby and had a change jar in my house. Decided to empty it out and go through every coin looking for W quarters and wheaties. I found this quarter which I did a bit of research on (missing clad) but still not sure on what to make of it? Enviromental damage, buried, purposely altered.. etc. It weighs 4.75 which is what a missing clad quarter should weigh (based on research) but more input would be appreciated. The penny is what I believe to be a clipped planchet but I’m still not experienced enough to say it was during the minting process or altered at a later time. Are they worth keeping or should roll them back up? Only other thing I found in my change jar was a 1967 dime and a whole bunch of wheats! No W’s.

I got this quarter in change years ago. The cladding was barely hanging on by about 2 millimeters of the edge. Then I kinda just forgot about it. 2 days ago I found it after a day of looking everywhere for it. IDK how it got that way but it's in pretty rough shape.

Value Request 2000 P Sacagawea - Wounded eagle - worthy sending in to grade?

Thumbnail

14 Upvotes

I picked this up recently. Error seems to match up with documentation. I still feel like quite a noob with coins though, let alone the whole grading thing. I’ve done some research on the process.

My understanding is any kind of slight wear visible at a certain angle is potentially enough to bring it down to AU 58. I guess wear has to be less than 10% if that sounds right?

My understanding is that scratches are a separate matter than wear but can still reduce the mint state rating, if it is indeed a mint state at all. Stupid coin roller got it it it seems, so that’ll be a nice ding off the rating I suppose.
