CoinFactsWiki uses a copyleft license for all text, images, and other content on the Web site. Anyone can use CoinFactsWiki content according to the terms of the Creative Commons Attribution-ShareAlike license. And anyone can contribute their own or other people's text and images, as long as the work is their own or available under a compatible license.


If this seems confusing, skip down to the FAQ.

All written contributions to CoinFactsWiki are and must be licensed under Creative Commons Attribution-ShareAlike 1.0 (CC-by-SA 1.0) or a compatible license (e.g., Public Domain, CC-by-SA any, dual CC-by-SA/GDFL any, etc.). Consequently, all redistributed and derivative works of CoinFactsWiki text must also be licensed as CC-by-SA 1.0.

Files uploaded to CoinFactsWiki are and must be licensed under any of the available options in the pulldown menu on the upload form. Consequently, all redistributed and derivative works including CoinFactsWiki images and other files must provide file-specific attribution and licensing information, available on the individual file page.

Two small subsets of images on CoinFactsWiki may be copyrighted, and not available for redistribution or derivative works, although these copyrighted images will never appear in a CoinFactsWiki article. For more information on these narrow categories of copyrighted images, see Template:Copyrighted.

Things for users to know

Copyleft means that every single author, editor, illustrator, , factchecker and photographer who puts their work into CoinFactsWiki gives you the right to read, copy, print, save, download, read aloud, project, modify, email, distribute, sell, photocopy and correct their work however you want to.

The only restrictions are that:

  • if you distribute it, or derive new work from it
    • you must give attribution to the creators
    • you must retain the work and any derivative works under the same licensing.

In other words, we give you practically every freedom within the boundaries of the law to use the information in CoinFactsWiki, except the freedom to take that freedom away from others.

The license we use is the Attribution-ShareAlike license. It's a piece of legal documentation created by the great people at Creative Commons that basically says the same thing as above: give WikiNumismatists credit for their work, and share with other people.

If you want you can read the full text of the Attribution-ShareAlike 1.0 license. For the purposes of the License, a Work is the formatted text that makes up a single CoinFactsWikiShared article. Each file individually is also a Work for the purposes of the License.

In addition, there may be other restrictions on use or distribution based on law in your country or state; in particular, consider privacy rights for photographs of people and derivative works for photographs of buildings and artworks.

Lastly, to the extent possible there is NO WARRANTY on any of the articles or images in CoinFactsWiki. People make mistakes. WikiNumismatist try their best, but none of the creators of these pages are responsible to you in any way for any injury or discomfort you endure before, after, or during your visit to CoinFactsWiki. See the License above for details.

Things for contributors to know

Copyleft means that every single yahoo, nutcase, screwjob, charlatan, shyster, weirdo, freakazoid, mouthbreather, goofball, lamer, cheater and jerk will have the right to read, copy, print, save, download, read aloud, project, modify, email, distribute, sell, photocopy and correct your work however they want to.

In particular, your work can be ruthlessly modified, edited, or cut from CoinFactsWiki altogether by other WikiNumismatists. It can be photocopied thousands of times and passed around as flyers by itinerant vest pocket dealers. It can be put in Hollywood movies, and it can be projected onto a screen at an outdoor rave. It can be used for commercial ventures, advertisements, or other purposes (with some restrictions - see privacy rights) without your direct control.

In return for your incredible generosity, you will have the knowledge that you are helping numismatists all over the world, and that all copies made of your work will be attributed to you, and that everyone who derives new works from yours will have to be just as generous as you are. And, of course, you get to use all the other work in CoinFactsWiki Shared the same way; but you don't need to contribute to do that.

You'll also get the pleasure of collaborating with hundreds of other WikiNumismatists just like yourself. You'll get free spellcheck service from nit-picky folks you've never met. You'll work together with people you don't know to make better pictures, text, and images than you've ever dreamed of. You still retain the copyright over your own work, and you can use it any other way you want (even if it's not compatible with our license!). By writing on CoinFactsWiki, or uploading photos and images, you're using a license under which all our work is available - making it simpler for everyone.

Now, the hard part: because of the Attribution-ShareAlike license, you are legally responsible not to put other people's copyrighted work into CoinFactsWiki without permission. You are responsible for getting model releases from people you take pictures of, and you are responsible for any libel you include in your articles.

Before editing CoinFactsWiki articles or uploading pictures, you should read very carefully the full text of the Attribution-ShareAlike 1.0 license, and make sure that you agree to it. For images, it's important to mark the image as either your own work, or give information on who made the picture and why you think it's acceptable under the broad terms of Attribution-Sharealike that govern CoinFactsWiki's licensing. See CoinFactsWiki Shared:Image policy for more information.

We want to make the best possible numismatic guide, with the most brilliant writing, the most up-to-date info, the most awe-inspiring photos, the most detailed and readable images. But no one item is worth putting yourself and this project in legal jeopardy. If you have any questions about the source of something you want to put in CoinFactsWiki, ask about it first. When in doubt, leave it out.

Frequently asked questions

What do I need to do to get writing?

Nothing, just plunge forward! Whenever you save something you write, you automatically license it for use under CC-by-SA 1.0. So all you need to do is get started writing—if the text is your own original writing, don't worry about licenses.

Can I copy text toCoinFactsWiki from other sites?

No. That is, unless you are the original author of the text, or the text on the other website is either Public Domain or has been explicitly licensed as compatible with Creative Commons Attribution/Attribution-ShareAlike 1.0. For the text to be Public Domain, it basically needs to be created by the US Federal Government, or have a statement on the website saying it is released into the Public Domain. If you are the original author of the text, note that on the article talk page, or else someone will likely remove it as a copyright violation.

Lack of a copyright notice does not mean the content is free to re-use—all online content is automatically copyrighted unless the author explicitly states otherwise.

What do I need to do to get uploading images?

First, you should register an account on CoinFactsWiki, the central repository for CoinFactsWiki files. Then, go to the upload screen, where you select the file to upload and enter an upload summary. The summary must include a choice of license from the pulldown menu, as well as attribution information indicating how you wish to be credited. If the image is not your own, be sure to provide accurate licensing and attribution information, as well as a link to the source from which you got the image.

The simplest way to make sure everything is correctly documented is to use the image credit template (see How to upload files for detailed instructions). If the template seems too intimidating, an acceptable comment might be:

Image copyright 2006 by [[User:CoinFactsWiki]], dual-licensed under the CC-SA 1.0 (or later) and the GFDL. Taken by [[User:CoinFactsWiki]].

There are some additional restrictions in specific cases (such as when photographing people) so please also read our Image policy.

How will I be attributed?

You will only be attributed for text contributions if you register a user account. The attribution will be reflected on the history page of each article. If you register, but decline to enter a "real name," you will be attributed by your user name.

For files you upload, you must provide the attribution information yourself in the upload summary. So, just indicate however you want to be attributed as you upload the file!

Can GFDL content be used on CoinFactsWiki?

No! See Why CoinFactsWiki isn't GFDL. This means that most content from CoinFactsWiki and Wikimedia Commons cannot be directly copied to CoinFactsWiki.

Can content from other sites be used on CoinFactsWiki?

Maybe. Text from other sites can be used only when it has been explicitly licensed under the Attribution Share-Alike 1.0 license, a compatible license, or released into the public domain. When copying content from another site be sure to provide proper attribution, as required by the CC-by-SA license. This means citing the license, author and source of images on the image page, and noting the license, author and source of text content on the article talk page.

If content is available free-of-charge, can it be used here?

Probably not. Just because a brochure, or other item is given away for free does not mean that it has been freely licensed. For content to be usable on CoinFactsWiki the content copyright owner must agree to license it under the CC-SA 1.0 or a compatible license.

How should I ask for permission to use text from a forum reply on CoinFactsWiki?

The following template can help. Please quote your original message and reply to it at the respective article's Talk page. You may provide attribution to the original author(s) listing them by a template like en:Template:Attribution.

Hi (person name).
Do you mind if I use some pieces of your post (<forum post URL>) to contribute to an article on <destination> at Wikitravel, a free online travel guide written and edited entirely by travelers from around the globe?
The current edition of the article I am going to update is here: <article URL>.
CoinFactsWiki requires that all the content is licensed under Creative Commons Attribution-ShareAlike 1.0 license. Basically this means that your content:
- can be distributed by others, as long as you are credited as the author
- may be further edited by other contributors
So do you mind if I use your text at CoinFactsWiki?
