PLEASE READ FIRST: How-to Guide for r/coinerrors
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:
- Do your own research before posting a question.
- Post Original Content
- Stay on topic and be respectful of the hobby and your fellow collectors.
- Keep it clean - this is a safe place for people of all ages and backgrounds.
- Being civil to other people is not only appreciated here, but also a requirement.
- No self-promotion or commercial activity is allowed; no links to your blogs, websites, or social media.
- No spam.
- No politics or religion, especially divisive comments that lead to heated arguments and incivility.
- No reposts.
- No Misinformation

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

Error Is this a detached lamination error or maybe a strike through?
Please educate me, if it’s a lamination error then it’s a very odd shape.

Discussion Die polish marks?
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.

Is this an error? Missing half of date - 1915 Barber Dime.
The 19 is missing…. Well a very weak strike. Is this considered an error? Does not appear to be done intentionally. Would it be worth grading? Any advice greatly appreciated - thank you.

Is this an error? Is this a double edge?
I'm not sure if this double edge at the top is considered an error. Can anyone identify it?

Is this an error? Possible s/s?
I’ve been doing some CRH to build a penny collection and found this really nice ‘69 S. I’m uncertain if this is a s/s. I don’t know of it being an official error, but it looks like something underneath might have been chiseled off. There is also serifs, and it seems like something under the top part of the S mark.

Is this an error? Post damage or mint error?
Sorry for not the best photos but does this 1915 penny look like a mint error or damaged afterwards? I pretty sure it’s post damage but not 100%. Seller told me she thought someone put it on a train track but that’s only speculation. Any answers would be appreciated Thanks

Is this an error? Die gouge?
New quarter. I can't tell if this is pmd or a die gouge or what. The curve lines seen to go with the curve of the coin too well. It's tough for me to tell if it's raised or grooved.

Attribution Assistance I can't tell what exactly is going on.... TIA for the help!
Got a weird one that I can't exactly tell what it is or even feel "close" to understanding.
2000 (P) Lincoln cent - weight and diameter check out along with thickness. What caught my eye is it seems like there is almost a double rim?
I trying looking it up, but most results were just about the wide AM.
On error-ref, I saw perhaps being an abnormal edge upset mill error, but the site says that usually occurs with some sort of offsetting - which I'm not seeing on either face.
Another thing I looked up was this possibly being a double strike, btu that seemed to tend to have either doubling or offsetting. In the same vein, broadstuck is off the table since the diameter checks out.
The only other thing I can thing of is that this is very late stage die deterioration, and perhaps a ring around the edge of the die broke? I just don't know.
The other option is PMD, but it looks to be too perfect around the entire edge to be done with spoons etc... and it seems like the letters pull to the edge.
Thank you all in advance!
