I do not think there is an "official" point of view. I will share my personal opinion.
Die clash is a mint defect. Whether or not it reduces the value of a given coin is up to the collector.
For many series, "deep" collectors will pay slight premiums or even high premiums for spectacular die clashes.
Flying Eagle cents,
Morgan dollars, the Liberty Seated series, and two cent/three cent pieces are examples of series where clashed die varieties are generally accepted, and to some, highly desired based on the extent of the clash and the clashed coin's scarcity.
In this case, I would defer to one of the more avid 3CN collectors/students here, but I should think that given the strength of this clashed pair & the results on the coin, that it would not affect the technical grade in the least, and might be very interesting to error coin enthusiasts, 3CN variety collectors, and clashed die fans in general. Personally, I love this coin and would gladly pay to own a similar specimen.
I do not think that in modern grading a genuine mint error clashed die will make much, if any, impact on the technical grade of a coin at any major
TPG.
That being said, there are plenty of collectors who prefer non-defective coins and who would not really be interested in this particular coin due to the clash. To each their own.
The same applies to other mint-caused errors or issues (die cracks,
Retained Cuds, rusted dies, MAD, off-center/broadstrike/OOC, double struck, flan clips, hub doubling...) -- some collectors greatly prefer and value these coins and others do not want to collect them.
Just my 3 cents. AB
