I do not see anything suspicious. If it is modern dies, the engraver did very well capturing authentic
style. Your photos show die cracks, along with flow lines and die wear that suggest it is struck, and struck with dies that have been well used, supporting likely authenticity. Have you checked the
fake coin reports for a match? Look at the die cracks, if they appear to be actual cracks with rough interior surfaces, the coin is almost certainly not
cast.
