1878 8TF A1n Reverse, But Can't Find The Obverse Makers

Hey guys, this Morgan recently came through our store, and both me and my co-worker agree that it's an A1N reverse, which would make it (hopefully) an incredibly rare VAM, but neither of us can pinpoint which VAM it is, and believe it could possibly be a new VAM with the A1N reverse. Can I have some help in figuring if it's possibly a new VAM or if we're missing something obvious?

The coin in question:








Reverse diagnostics:

Tailfeather Design:





Reverse Doubling (shows well on the R as well as the berry in the wreath):





Interestingly enough, this coin does not have the thorn in the lower crook of the N. the die polishing in the upper crook, however, is there. Though you can't see it in the photos. This kind of worries me as I might be missing a different reverse variety that I ruled out prematurely:






As for the obverse, there are very few markers that show, on the coin, there looks to be evidence of a spiked eye, but the markers on VAMWorld look different to the one on this coin, there's also a pretty major die break above the eye which is not stated as a marker on any of the coins:






Based off of this evidence, we are planning on sending it in to PCGS, but before we do, is there anything major we could be missing that would rule it out as either an A1N or a discovery piece?

Thanks for the help!
