The letter J did not yet exist. Jesus was originally spelled with an I.
The cornerstone of a building built in, say, 372 would have I372 carved in it. A modern observer would think it read 1372 and was therefore a thousand years younger, that pretty much nothing of note was built before 1000 AD!
The correct sequence is: "A.D. ####."
