Yes, these are NGC pictures. Full coin (both sides) is/are pictured. Is there anything specific you are looking for?
It was submitted by a dealer as a regular world coin submission; error or variety designation was not chosen nor paid for. So, no, NGC graders didn't notice jack.
I'm certainly no expert, and it certainly could be double struck, but I would think more would show up on the reverse as well if that were the case. As for there not being more doubling in the letters, as I understand it in making the die the first impression of the hub is sometimes rather shallow, affecting mainly the higher details. If that is the case on this one, the first impression was so far off that it may have been realigned before a more definitive pressing, which would leave the kind of doubling seen here. I own a 1947 Costa Rica 10 Centimos with clear DDR, but it only shows in the central area, on CENTIMOS, with no doubling at all in the outer lettering.
I think you are spot on, Neal. I got in touch with an expert and they relayed that they believe this is a Doubled Die and following is what they had to say: “It wouldn’t make sense for strike doubling to only affect the high point. If anything it should affect the field areas. It’s akin to a doubled ear Lincoln, just much more dramatic. What likely happened is that the die was tilted away from the hub when initially hubbed, so the high points of the design (also high point of the hub) came into contact with the die off-center and at an angle. Then it was rehubbed properly. This is a different sort of situation from the typical doubled die with rotational doubling around the devices from hub/punch misalignment”
