Is this coin real One side has shield-confederate states of America half doll Other no picture just words CSA New Orleans 1861 4 originals struck by order?

This coin is likely a replica or a reproduction. While Confederate half-dollars were authorized by the Confederate government, only a handful of originals are known to exist, and they are incredibly rare and valuable. The genuine coins would have a high relief and clear details, and they would be made of silver. If the coin you have is made of a base metal, such as copper or brass, or if the details are not sharp and the relief is low, it is likely a replica.

Additionally, the fact that the coin has the words "4 originals struck by order" on the reverse suggests that it is a reproduction. Genuine Confederate half-dollars do not have this inscription.
