548 43d Street
I already have a 1901 mark from Peterson & Adler, but here’s another one. This is right at the edge of the strip of homes that was wiped out for the Grove-Shafter Freeway back in the early 1970s.

341 49th Street
Here the “1901” date was made by filling in the last zero in a “1900” stencil. Another example is the 1932 mark.
