Just to give you a trio of respondents singing in the same key: There are indeed a number of circumstances where you can put holds on U.S. Treasury checks. Inability to verify a prior endorsement would be an example.
The problem is that any hold you can impose is not an effective risk management tool; the hold will expire long before payment on the check is declined or you get a reclamation notice.
Know your customer.
