This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 100,785 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 100785 first appears in π at position 272,161 of the decimal expansion (the 272,161ordinal-suffix:st digit after the integer 3).
