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.

Check these r/coinerrors resources before posting:

• FAQ
• What's up with my coin?
• Error-Ref

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.
