Leaning towards MD with a bit of
DDD as well, BUT, would need sharper addition pics of the rest of the reverse.
If this were FS-801, there is pretty substantial doubling/tripling throughout the reverse devices. Very obvious and strong spread in FIVE CENTS.
DDR-002 doesn't have nearly as strong a spread, may be difficult to attribute on a heavily circulated example.
Either way need additional pics, but right off the bat, leaning towards not a
DDR.
