Again, the time for comment is short, only until 9/22. In addition, the State Department now evidently wants to avoid being deluged with faxes from concerned coin collectors. As a result, most public comment now must be made through the following website: http://www.regulations.gov/

I hope to be able to comment on this material soon.
