1963 as Burt said. The production year is the last two numerical digits prior to the -C in the DSA number.

Yep 1963 this one is super easy to identify as upper pockets have specific design without "bellow". Also if I remember correctly newer type of buttons can be also find from 1963 on m51 field coats. This one contract was made by the Southern Athletics INC.
Looks a bit familiar to me
