looking for an article from old board on coin circulation

There was an article posted on the old RealCent board about how coins circulate, with the Mint, Fed Reserve branches, and armored service company relationships explained. I think I posted the only comment to that original post, just so I could find it again. But now, of course I can not. I tried the search feature on the still available old site. Does any one remember the article, or where I might find it?.
