Looking at this pic in detail, this looks like it was slowly heated and manipulated after being made. Would not necessarily mean embossing would be gone, but shape can be distorted.
Back to insulators that are altered (this is relevant), all the carnival coated Mickeys were re-heated, then sprayed with tin oxide. Never seen a bad or slumped example, or compromised embossing. The fraud was do be convincingly. Also with a suspect color (tried and proven), an irradiated insulator that was slowly heated will have the ability to change colors. Cornflower or sapphire is a common outcome on some nuked-heated aqua insulators. NEGM beehives being the worst. Anywho, check the threads on a standard threaded pin, and if they don't line up nicely with the insulator, it is highly suspect. Even if the shape or embossing is unaffected.
