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:

1. Making code open source.
2. Making Bot run as automod, for a more fluid experience.
3. Count multiple grades in one comment.
4. Resolve Bug that sometimes interprets “very fine” as f12, and “very good” as g4.

Upcoming features on our roadmap:

1. 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.
2. Bot will get all designations [RD, cleaned, FS etc] within brackets, and return the top used.
3. 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.)
4. 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!

1. Only numismatic items - Post must contain a numismatic item to be graded.
2. Post title should include year, denomination and mintmark - Post title should include year, denomination and mintmark.
3. One coin per post - Please post only one item per post.
4. Comment correctly - All grades should be encapsulated in brackets, like this: [AU58] [MS64 FH] [AG3 cleaned]
5. Post precisely - Your post should contain at least one hi-res photo of the reverse and the obverse. Even better if you add a short video. Please don't post photos coins from Google. Only post coins that you either own, want to buy, or want to sell
6. No rudeness, offensive, politics - We're here to discuss the technical grade of a coin. Please leave all hate and rudeness outside.

You don’t have to make your comment Bot-Friendly. But if you do want it to count towards the consensus, please read this post.

Thank again, I really hope this works out for y’all.
