I interpret that disclaimer as "it's cleaned, don't try to come back on us if it doesn't straight grade". They don't disclaim authenticity, and even if they did, they'd be in a world of hurt if they tried to sell fakes. That being said, I'm not comfortable authenticating this date myself, and I don't know how well they can do it, so... pass.
A while back I posted a pic of mine and someone had an overlay that showed the mint mark location was correct. Don't know if that is a valid way to verify or not. Bought mine from a dealer that would refund.
I always assumed that the period between the V and D was usually almost right in the center between the V and D. At least mine is.
Here they show the four mintmark locations along with some other identifers. https://coinweek.com/from-the-dark-corner-an-authenticated-1909-s-vdb-lincoln-cent/ to me the S looks wrong. Should be a box, the S looks too tall The top and bottom of the S looks too thick The N on the reverse looks wrong plus the already mentioned wrong dots
I would say it's an added S, added VDB fake. https://coinweek.com/counterfeit-coin-09-s-vdb/ also shows the diagnostics. The subject coin VDB looks a lot like the added VDB in the article. Mint mark is closest to position #3 but it lacks the clockwise rotation. As noted, it seems too tall, and lacks the die chip inside the upper loop all the real ones have. Plus it just looks like it was stuck on there. I wouldn't touch one of these unless it was certified. It's the number one most counterfeited coin.
