Very hard differentiate by the die markers with these brown copper coins by all examples i see its an wddo oo3 any feedback
Well, I think it would have to be a "new" discovery; the major 72 DDOs of Wexler & Wiles (CONECA) appear to be Class I (Rotated Hub Doubling). With that, you will see the doubling effect on all of the design elements, with the strongest occurring around the rim. The spread is often dramatic (like the 55 Lincoln), but even if not all that strong in appearance, you will be able to discern the occurrence of doubling on elements completely around the rim. In your coin's case, the only area that I can see evidence of possible "doubling" is on the date; even with that, from the look of the "2" I would guess that what you are seeing is "Strike" doubling. Of course, that's just my view of it. Semper Fidelis.
