My post here is twofold:
First, no serious collector or enthusiast should approach authentication of any article based upon item condition. There are very many legitimate vintage items that have survived into the present day in as-new condition, and conversely there are very many fakes that exhibit deceptive "age and wear". Those who profess to know nothing about a particular field of study yet state something cannot be authentic because "it looks too new" do a disservice to what may actually be a perfectly fine period original artifact. One must take a studious approach toward determining authenticity which will encompass an understanding of original materials (cloth, metal, leather, etc.), design, construction, and particular manufacturer traits (provided the maker is known). Photographs of key details of any item are often essential toward this end, otherwise there can be lingering questions that might only be resolved by way of a direct hands-on examination.
That being said, the cap in question exhibits the wartime maker logo which has been identified as Oskar Hertlein of Erlangen. This logo appears mainly in Heer visors but this company produced visors for other service branches too. It is somewhat common on many civil and political caps as well and as such a fair number of fire police, railway, etc, visors have been used by forgers to create more desirable SS visors by way of removal of those original liners to use toward construction of "Waffen SS" visors. Additionally, it is also one of the most faked logos which can complicate the issue further. Since the IMA photos of the subject cap lack illustrations of areas necessary for a complete analysis of construction (under the sweatband images are crucial), I would not feel entirely comfortable with what can be seen in the current images and further scrutiny is certainly justified. But that is a moot point since there is no opportunity to see additional details of this cap.
Lastly, a legit WSS EM/NCO visor is not realistically priced at $7500 unless one were an absolutely superb piece. Obviously there are certain dealers that would use that price point, or higher, for the average WSS EM/NCO visor but examples can be had in collector circles in the $4k-$6k range.
