I ordered one, will post a pic when I receive it for those that are interested!
Also, I think I found a pretty close match to the eagle seal from the top of the creds, it's not exact but Its pretty close! Its from a US civil war era enlistment document rather than anything to do with the US Marshals service. A little more digging around that era might turn up an exact match....
Finally, a really clean scanned image of the Seal used for the Marshal creds.
