This is a fun coin. It is a MDS 1930-S CONECA RPM-004 (Wexler has it as WRPM-005) with a nice lamination from about 12:00 to 4:00 on the reverse. Both Dr. Wiles and John Wexler list this as S/S Northwest, but I have always thought that it should be S/S/S NW and SE.
Like all the 1930-S RPMs, it is common, but a bit pesky to spot in the wild. This is another coin from my junk boxes, all pulled from circulation back in the 1960s.
Here are the date and mm:

Here are the obverse markers:

And a cheat circling the die gouge and pointing to some of the remaining MDS die scratches below the front of the portrait. The die scratches disappear quickly in MDS, but the small gouge is the lasting marker.

Here is the reverse marker. It is also really weak in MDS.

And a cheat pointing to the very light remaining marker, the bowed scratches between "R" and "I" of EPU:

And the fun bonus on this critter, the reverse lamination:
