1948 S penny in remarkable condition. 1 1

[Mr.Bill347]

seems to be MS/BU is this common? Appears the same as a 2020.

The obverse, which is the only side you provided, looks fairly worn to me.

[Mr.Bill347]

Here it is next to 1947 MS66

That comparison doesn't make the wear go away. I think you are going too much by color and not enough by observing the high points. Plus, while the slab is completely irrelevant here, that photo is so blurred that it's sort of doubly irrelevant. If you want a firmer opinion, you'll need to post sharp cropped photos of both sides of the first coin with improved lighting (which is not to say brighter lighting).

That coin looks like it has been cleaned.  Notice the shadowing around the lettering and devices, this is where the cleaning could not reach.

Whether due to light wear, cleaning or both, the coin’s condition is far from remarkable. Many dates of wheat cents were struck in such massive quantities, that even today, they’re readily available in choice uncirculated or better condition.

It’s remarkable by definition. After all, he remarked on it. As did others.
