B+
HistoryA character grade: shown, never part of Osborne’s overall grade.
Kansas towns list more on the Register than most of the country (a typical Kansas town has 5.1 per 10,000 residents, the U.S. 2.4), so Osborne’s 14.7 sits above most of its state (72% of Kansas towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B− to A. The pre-1940 share is a Census survey estimate (±6.5 points). Two sources give 1871.

What stands out about Osborne’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Settlers from southeastern Pennsylvania founded Osborne City in May 1871. They named the settlement after Vincent B. Osborne, a Union Army veteran of the American Civil War, after whom Osborne County also is named. Osborne City became the permanent county seat in November 1872. A district judge officially proclaimed it a city in May 1873, but the townspeople failed to legally organize a government. Five years later, a second attempt was successful, and the settlement was incorporated as a city in 1878. "City" was dropped from its name by the mid-1890s.
A bridge was built at Osborne over the Solomon River in 1878.
Osborne’s post office has been open since 1872. Another post office, Penn, opened and closed inside today’s town.
