Four letters between Charles B. Elder Jr. — on Trap Rock Material & Engineering Co. / Iron Mountain Trap Rock letterhead — and St. Louis numismatist Eric P. Newman, arranging the appraisal of a coin collection Elder inherited from an uncle. The letterhead is the earliest known documentation of the Iron Mountain Trap Rock name (Feb. 28, 1962; Gretchen K. Elder, president), proving the quarry business predates the 1966 mine closure. Newman's reply records his ca. 1959–60 tour of the Hanna underground workings (“watching the trucks operate underground”), and a May 1962 letter documents a fruitless local search for old Iron Mountain Company scrip.

The company town's own money — a surviving five-cent note issued by the American Iron Mountain Company, dated September 17, 1868, sold at public auction September 10, 2018 (PCGS Fine 15; severed and split with tape repairs; seven bids plus phone bidders). Heritage notes only three examples of the design offered since 2002. This answers the question Eric P. Newman posed to Charles B. Elder Jr. in 1962: the scrip existed, and specimens survive. Located by RM in the Newman Portal's scanned catalog archive, July 2026.

Free: PRNewswire, July 15, 2021American Iron Mountain Company Records (R0003), 1849–1855 — State Historical Society of Missouri, Rolla Research Center
One roll of microfilm: a pig-iron account (1849–1853) recording iron delivered at Sainte Genevieve and shipments to buyers, and a tally book (1852–1855) of ore delivered by haulers. Names James Harrison of Chouteau, Harrison and Valle as head of the firm and dates the company's acquisition of the property to 1845, in conflict with the 1843 date and "Conrad Zeigler" name found in published local histories. States the company built furnaces in 1846 and 1850, added hot blast stacks in 1854, and operated the property until 1893. Two related, uninspected collections are cited in this finding aid's own records: American Iron Mountain Company Metal Hauling Records (R0439), and Sainte Genevieve, Iron Mountain, and Pilot Knob Plank Road Company Records (R0747).

County place-name study. Entry "Haggai" documents a settlement between Iron Mountain and Doe Run that arose after individuals were required to build competing stores outside the Iron Mountain company's land concession, company stores being the only ones permitted within it. The entry cites the Handbook of Missouri (1881), the Rand McNally Guide (1890), and Miles' History of St. Francois County (1935), and cross-references a comparable case at Middlebrook, Iron County. The 1890 renaming (Hog Eye to Haggai) is corroborated independently by Robert L. Ramsay, Our Storehouse of Missouri Place Names (University of Missouri Press, 1952).

Researchers of this property regularly collide with two unrelated namesakes. The Missouri Mines State Historic Site in Park Hills preserves a lead-mining operation with no connection to Iron Mountain's iron works — its images are frequently mislabeled as Iron Mountain online. And "Camp Iron Mountain" was a Second World War desert training camp in California, sometimes erroneously grafted onto this property's Civil War history. Neither belongs in the Iron Mountain, Missouri record.
