For example, this file claims to show that the average maximum temperature in Brewton, Alabama (station #011084) was 59.7 degrees in January 1895

But when you look at their raw daily data, you can see that they don’t have any temperature readings for Brewton, Alabama prior to 1926.

I chose Brewton because it is the first entry in their database.

The third entry in the USHCN database is Fairhope, Alabama. There are no daily temperature records for Fairhope (station #013160) prior to 1957, yet USHCN2 reports their average raw monthly temperatures back to 1895.

Whatever USHCN is trying to pass off as raw monthly data, is definitely not raw data.
