Can You Confirm My Ability To Spot A Fake 1908-S Indian Cent?

I don't see anything to indicate any of these coins are fakes, what are you seeing that makes you think they are?

I really like to examine each coin raw, in hand under ideal point source lighting conditions, with a 10x loupe
just as the TPGraders do.

Can't do that if they are slabbed, and you wish to confirm weight or have XRF tested. If slabbed, the best you can do is a visual inspection to make your own confirmation that the grader was right.

Much harder for us to decide if fake or not, from on screen pictures.
Very difficult to photograph edges of coins that are slabbed.

Highest level of trust for slabs are for coins that were submitted by the top level numismatic auction houses, such as Heritage.

<<8 reverse dies used in San Francisco that year
@Zurie, thank you, that might explain it, now, where can I find a list of these 8 varieties?
Do you think this attached one in the photo is real and if so, which variety and grade would it be? I was also looking at the bottom of the ribbon to the left of the S and noticed a difference in addition to the position of the S itself. Would a change in variety only affect the position of the mint mark or could other things change also?

There can be minor differences from die to die due to die wear, die clashes, die lapping and polishing, and how sharply the die was made originally.
