A−
HistoryA character grade: shown, never part of Coburg’s overall grade.
Oregon towns list more on the Register than most of the country (a typical Oregon town has 2.9 per 10,000 residents, the U.S. 2.4), so Coburg’s 627 sits above most of its state (100% of Oregon towns have fewer) while its 102 historic buildings outnumber those of 90% 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 (±8.9 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1893 falls in the same era, so the grade doesn’t depend on which one is used.

What stands out about Coburg’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The city was originally named Diamond after John Diamond, an early pioneer in the area, on whose land claim the city was located. The city's current name comes from a stallion that was named after the Coburg district of Bavaria, Germany, from whence the horse had been imported. The Coburg Historic District was placed on the National Register of Historic Places in 1986. The period of significance of the buildings in the district dates back to 1875. The citizens elected Carol Heinkel first woman mayor in 1988. The City installed a sewer system in 2011 to 2015, leading to a new period of growth in both residential and commercial investment.
