First, a note about links to articles from Coins Weekly. I've noticed that their Article of the Week always has the same URL; it works during the week the article is first published, but the next week it points to a different article.

Once an E-Sylum issue is out the door I have time for little else but the next issue. So I can't promise we'll ever go back and update links in our archive. So be aware of this problem, and if you need the see the original of a Coins Weekly featured article, just search in their archive - it's there somewhere.

With help from Björn Schöpe of Coins Weekly. I learned that the article's permanent URL can be found via a search on their archive, so I've started doing that. The below link is to a permanent URL.
