Hadn't even thought of the possibility it was a counterfeit type. Here is a picture of the stamp in question on the left with a normal one on top. Due to the poor printing I expect others will confirm it is counterfeit. Made it through the postal system just fine.
Mark, just in case you are not aware the USSS May 2020 issue has an article on 2017 counterfeits. Also, PNC3 has had numerous reports of fake coils bought off of ebay
