I'd be careful. I'm not a lawyer, and this is not legal advice, but that page only refers to posession. I seem to recall things existing that are legal to have, but illegal to purchase.
I have no intention of buying the money I was just curious specifically about the law surrounding the issue. If I did intend to buy it (for whatever reason) I certainly would check further. I just found the language on the page interesting I didn't expect it to discuss the issue in that way.
