Possible Genuine 1856 Flying Eagle Cent? Looking For Opinions

I'm considering purchasing a collection that includes this coin in the 1856 Flying Eagle cent slot. These are the best photos the seller has provided so far, so unfortunately the image quality isn't great.

I know altered-date 1856 Flying Eagle cents are extremely common, particularly altered 1858s, so I'm assuming it is not genuine unless there are convincing diagnostics otherwise.

The 6 is what concerns me most—the positioning looks a little unusual to my eye. Before I completely write it off, though, I wanted to get opinions from members who know the series better than I do.

Based on what can be seen in these photos:

I realize nobody can definitively authenticate a coin from blurry photos, but I'd appreciate any observations before I decide whether it's worth pursuing further.

Thanks!
