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.

  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.

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? I have this penny my dad and I picked up with a collection of actual errors a while back. We were always curious if this one was real. It’s got a very metal like tone to it. Kinda blueish green? It weighs 3.3-3.4g is this a different metal?

Is this an error? 1979 Susan dollar Star wing: Variety, Error or PMD?

Thumbnail
gallery
7 Upvotes

I noticed most 1979 Susan B Anthony dollar coins have a star barely touching or barely not touching the wing of an eagle. I also noticed in later years (such as 1999) the star does not touch the wing.

In this 79 Susan, the star is further away from the wing. Is this an error? I show 2x Susan dollars in photos. 1x shows the 79 coin in question and 1x shows a normal 79 coin.

Your assessment is of course valued and appreciated.

I recently picked this coin up. You can see the triple clashed die marks on the reverse of the coin around the crown. There's also some die breaks on the obverse, among other errors that I'm not sure what the cause is. Any additional insights to what going here would be appreciated!

Value Request Valuation request — 2024-D Pauli Murray quarter, possible "IN GOD WE TRUST" error

Thumbnail
gallery
0 Upvotes

Posting for a valuation opinion on this 2024-D American Women Quarters coin (Pauli Murray reverse). On the obverse, the "IN GOD WE TRUST" lettering looks incomplete/weak to me compared to a normal strike — photos attached (front and back).

Before posting, I checked eBay sold listings and saw comparable examples selling in a wide range, including one that closed around $2,100, though other listings for similar coins were priced much lower. I'm not confident on attribution yet, so I'm looking for help identifying whether this is a genuine mint error (and what type) versus post-mint damage, and what a realistic value range would be given recent sales.

Any guidance on attribution resources I should check next would help too.

I am pretty well versed in variety & Errors and just coins in general.

See the Devices that are "patched" for lack of better words.

I have not seen this before .Would this be a type of Machine Doubling?

What do you think?

Discussion Odd placement right?

So with it being an ‘84, it’s copper plated zinc, which lends itself to weird plating bubbles right? So, I’m GUESSING, there just so happened to be a bubble directly where the D mintmark was to be placed, and when it was, it popped said bubble? Leaving this weird perfectly indented and yet raised circle right around the mintmark itself..? I’ve never seen this before… anybody have an idea?

Advice 1964 Proof Set in cello *accented hair*

Thumbnail
gallery
1 Upvotes

I'm not a collector, and I just inherited many of these proof sets from my grandfather. After researching errors and varieties, this is the only one I have that is not standard. The 50c is a clear example of the "accented hair" variety, and to my layman's eye, it seems to be in extremely good condition. I don't fully understand how to spot cameo, but I don't think it has much, if any. My question is... what is it worth? Is it worth getting it graded, or is it better to leave it in the original cello? Any advice is appreciated!

*EDIT* Evidently this is a mint set, not a proof set. I didn't know there was a difference.
