I have not seen anything offered by any state agency. The Sons of Confederate Veterans is offering some sesquicentennial items to members and non-members.
I purchased a very nice looking auto tag for the front of my truck. The have some other items as well. As someone suggested above if there is demand for the someone will supply. This is a link to the SCV online store

You can select the confederate gifts category which contains items available to non members.
