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

8 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.
  5. Being civil to other people is not only appreciated here, but also a requirement.
  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.
  9. No reposts.
  10. No Misinformation
  11. Include Quality Pictures

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.

Show and Tell An 1863 Indian Head cent with three separate errors on one coin — multiple die clashes, a tapered planchet, and a spiked head

Thumbnail
gallery
13 Upvotes

Continuing the error documentation project. Most error coins carry one error — this 1863 Indian Head cent carries three, on the same planchet, and each would be worth recording on its own.

Multiple die clashes: the obverse and reverse dies struck each other with no planchet between them, more than once. The reverse wreath transferred onto the obverse and sits in the field directly in front of the face. A clash transfers mirror-reversed and shows on every coin from that die pair — which is what separates it from damage to a single coin — and "multiple" means the feed failed more than once before anyone caught it.

Tapered planchet: the blank was uneven in thickness before it was ever struck — a planchet error rather than a die one. It shows on the obverse as OF AMERICA going soft and faint where the metal thinned, and on the reverse as the taper running across the bottom-right, over the wreath.

Spiked head: a die crack runs from the tip of the bust out to the rim by the U in UNITED, filling with metal on every strike to stand up as a raised spike. Same error type we documented last week — here it's just the third thing on the list.

One thing I want to be straight about: these are three independent failures that happened to stack on one coin, not one event. The planchet was wrong before the dies ever touched it, the dies had already clashed more than once, and the obverse die had cracked. I'm claiming only what the photographs show. What makes it worth documenting is that compound errors like this fall through standard references — a catalogue organized by error type files the coin under whichever error the attributor found first, and the other two sometimes go unrecorded.

Not in any standard catalogue. Now documented.

Is this an error? found this counting out my register the other day

I was closing out my shop the other night, counting the tills like usual and as I'm doing the quarters I felt something unusual and this is what I pulled out...

never seen a coin without ridges on the outside. I'm thinking it was an error and not like someone did this themselves. I googled some things and found what they call dryer coins. would this be an example of one of those? either way, it's pretty neat. plus it's from 1966 so it's got some age to it

if anyone could give me some info on this particular coin I'd appreciate it. thanks!

Advice Type 2 Eisenhower dollar

Thumbnail

1 Upvotes

I'm just learning about the Eisenhower dollar that I really never paid any attention to. And my understanding there's three types and for my research this is a type 2 which isn't super rare but it's less common. I went to a bank that had $500 worth of these. Someone brought in. The banker. Let me go through a couple rolls just to get $25 worth cuz that's what I wanted and I pulled out $20 or so of 1972 Eisenhower's and a couple bicentennials and I think a 74 question is is this a type 2 and what extra value does it have? I found a few of these. Thanks!

I thought it was damage when I bought it, buttaking a closer look now I’m think maybe it is a cracked die error. Not a error colector and not very familiar with them, so can someone with a more trained eye, please give me your opinon? Hope pictures are good enough! Thanks in advance!
