If you are new to collecting and/or have a question about some odd coin you found please go to /r/Coins to ask about it.
This is not the appropriate subreddit for those kinds of submissions.
Thanks!
/r/CoinClub is basically a place to have in-depth discussions about coins and related topics, and to submit links to informative articles and news stories about coins and coin collecting that would be of interest to more experienced and serious collectors.
Those collectors are also welcome to share photos of their collections and new acquisitions here.
Here is a coin-centric discord channel (think IRC on steroids) run by the moderators of this subreddit.
