Wikipedia Accuracy

I view Wikipedia articles like term papers. Always check the references!

There are footnotes on most of the articles:

http://en.wikipedia.org/wiki/Americ..._Eagle#Notes

Many of the references are to published (printed) sources, so it might require a trip to the library to verify them.

But a lot of them are online, so be cautious of where they link to. That is, decided how trustworthy the source is.

Those are basically a great source for information. Pending on how much you want to know about anything, Google is also sort of great.
For example if you go to Google and type in American Silver Eagles, you get this:
Results 1 - 10 of about 728,000 for american silver eagle coins.
I know that many are just advertisements but if you really want to learn about them, after 728,000 items, you should be quite the expert. That's the good news.
Now here is the bad news. If you took 5 minutes to check out each of those you would have spent 3,640,000 Minutes or 60,666.667 hours or 2,527.778 days if continuous for 24/7. Even worse is if people added more while doing this.
Have fun.

I would not trust completel Wikipedia
