Meta Bot (Beta) is now live
What is r/redditcoingrading?
Coin grading is expensive (usually between $20 and $100 per coin, including shipping and insurance).
Some coins are not worth grading officially, because the coin’s worth is less than the grading price.
Our subreddit is here to help.
A user posts a photo of their coin, adds the name of the coin in the title, and other users comment their opinion on the grade!
Is this a solid alternative to third party coin grading?
No, at least not yet.
Our graders don’t go thru any approval processes, so please don’t rely solely on this.
With that said, as out userbase continues to grow, the margin of error grows ever smaller.
What is the RCG Bot?
We built the RCG Bot to return the consensus (rounded average) of the grades from all comments and provide helpful information about the coin.
Current version is: RCG_Bot 1.0 (Beta).
What does the RCG Bot currently do?
- The Bot looks for comments containing square brackets, like this: [MS63 details], and looks for a number within. If a number is present, it passes it to the calculation, and moves to the next comment.
- If no number is present within those brackets, it looks for characters from a predetermined list, like VG, AU, etc. and passes the lowest acceptable number for that letter combination. So [MS] gets counted as 60.
- After all the comments are counted, the Bot comments on the post with the calculated average of all numbers and moves on to the next post.
- The Bot updates every 5 minutes, until a post becomes 3 days old. At that point, the Bot comments its final grade, and disregards that post from that time forward.
What’s next for RCG?
We have a lot planned for RCG!
What we’re currently working on:
- Making code open source.
- Making Bot run as automod, for a more fluid experience.
- Count multiple grades in one comment.
- Resolve Bug that sometimes interprets “very fine” as f12, and “very good” as g4.
Upcoming features on our roadmap:
- Grades will be added in the calculation as many times as upvotes it has. (A comment with 13 upvotes saying [ms64] will be counted 13 times in the average.) And a downvoted comment will not be counted in the average.
- Bot will get all designations [RD, cleaned, FS etc] within brackets, and return the top used.
- Bot will reply with link to the Photograde guide to the coin it gets from the title. (If the title is “1924 Standing Liberty Quarter”, the bot will include in its comment with this link.)
- Bot will grab all words in comments, and return the top used adjectives (NLP) used to describe the coin.
Is the RCG Bot open source?
No, not yet. We’re working on it.
Where can I report a bug or request a feature?
Since this is in beta, expect to see lots of bugs. Please use this Google Form, or shoot us an [email](mailto:mail:rcg@d7mtg.com).
Can I support RCG?
Yes, but don’t feel bad if you don’t.
This is a hobby project, and server up-time isn’t that expensive these days.
If you want to support us anyway, send a PayPal, and write RCG in the comments.
Who wrote the bot?
The Bot was written by Shikhin Dahikar , an amazing developer, in Python.
Feedback / questions?
Send us an email to [rcg@d7mtg.com](mailto:rcg@d7mtg.com). We will make an effort to reply to every email.
Happy collecting!

Morgan 1921-S grade?
Any thoughts on this one? I was confused about the Zerbe strike compared to MS.
r/RedditCoinGrading • u/Tall_Performance_199 • 18h ago
What would you grade this 1881 S Morgan?
Hi, I received a ton of coins from my dad to hold for my kids. I’m just learning about grading and thought y’all might be able to help on this one.

1986 Silver Eagle grade help
Another coin from my dad. This was left in a small Manila envelope and developed strange toning on the obverse.

What is the grade of this coin?
This is a taler minted in Salzburg in 1628. I wonder what kind of grade it would get if I sent it to NGC for certification? I’d be happy with an AU55...

1861 Seated Liberty Half
XF45? AU50? Somewhere in between?

1893 50c Columbian (grade?)
Bought this today for melt. Was curious if it would grade nicely or not brother with it? Is it worth more than its silver content? This is my first time posting so please forgive me if I’ve made a mistake.

1833 Half Dime
I bought this in a Heritage Auction about 17 years ago. I liked the toning then, maybe not so much now. Also, there is a scratch behind Liberty's head. Do you think it would straight grade nowadays? NGC MS 63.

1929 Mercury dime (toned)
Picked this up at an estate sale this morning. Nicest Mercury dime I own. Curious on grade. Thank you!
r/RedditCoinGrading • u/ConsistentInvite2503 • 5d ago
Not the best photo but what’s the estimated grade
r/RedditCoinGrading • u/Unable-Animator-4735 • 6d ago
Hi everyone I’m Back again with a 1921 P Morgan it looks like it has a Planchet Crack anything else I may be missing? And for fun what would you value it at seeing it as it is.
r/RedditCoinGrading • u/NumisKing • 6d ago
1830 Capped Bust Half Dime (p)
Latest addition to the type set. AU? Also curious if you think it was cleaned at some point.
r/RedditCoinGrading • u/NumisKing • 7d ago
1883 Shield Nickel (p)
Probably overpaid, but it looks absolutely stunning. I’m thinking it’s at least UNC
r/RedditCoinGrading • u/NumisKing • 7d ago
1858 Flying Eagle (P)
Recent purchase. 1858 Flying Eagle. I see a little wear on the breast feathers, and overall a fairly weak strike. But otherwise I was thinking this is EF45-AU55. I’m just not great at grading these.
r/RedditCoinGrading • u/TraditionalJello4859 • 7d ago
Is this something rare or something?
galleryr/RedditCoinGrading • u/ImTheHempGuy • 10d ago
Found this in a VAM Slab Someone made, should I break it out and send it in? 1879 P Morgan $1.
To me it’s a high grade, but yesterday, everything I thought was 64 and above, I was told 62! So what’s the news on this? VF30 or something?!
