This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 100,121 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 100121 first appears in π at position 476,503 of the decimal expansion (the 476,503ordinal-suffix:rd digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
