The 77 Indian and 93 s Morgan have many pick up points (PUP) on genuine pieces. It would be hard if not impossible to get them correct on a forgery. The 37 D 3 leg Buffalo is another example with many PUP. The 16 d dime doesn't have many and there were a couple of different dies used so you really need to know what to look for. The 09 s V.D.B only had one die and I'm always surprised how many fakes are out there. Most can be caught because it has the Philly V.D.B not the San Fran V.D.B
