Description :

An exceptional, cohesive historic study and cabinet collection of mineral specimens primarily documenting iconic mining districts of the American West and Pacific Northwest. Collected and cataloged in the mid-20th century, the defining feature of this estate lot is its remarkable historic documentation. Nearly every specimen retains its original, matching hand-written or typed collector's provenance tag—including a highly desirable 1938 dated label—safeguarding invaluable site data from localities that are now completely defunct or inaccessible.

Lot Highlights Include:

Pyromorphite (Little Giant Mine, Mullan, Idaho): A choice, classic cluster of well-formed, olive-green barrel-shaped prismatic crystals ("barrel xls"). Preserved with its original hand-written label explicitly dated 1938.
Rhodochrosite (Butte, Montana): A vibrant, highly aesthetic cabinet specimen featuring deep pink rhombohedral blade clusters embedded in matrix. A textbook classic from the long-depleted underground veins of the historic Butte district.
Cerussite & Malachite (Old Caledonia Mine, Kellogg, Idaho): A beautiful, high-contrast paragenetic combination piece displaying fragile, acicular white cerussite needles nestled within a bright green malachite crust over a rich iron oxide matrix.
Chalcanthite / "Blue Vitriol" (Evolution Mine, Coeur d'Alene, Idaho): An intriguing regional secondary copper specimen retaining an archaic label utilizing the historic alchemical terminology "Blue Vitriol."
Sodalite (Bancroft, Ontario, Canada): A rich, deep-blue saturated specimen displaying excellent coloration from Canada's premier mineral locality, complete with a painstakingly hand-inked chemical formula tag: Na₄(AlCl)Al₂(SiO₄)₃.
Priday Thunderegg (Oregon): A cleanly cut and face-polished nodular section showcasing the signature agate-filled core characteristic of the world-famous Priday Ranch deposit.
Polished Petrified Wood Slab: A large, attractive display slab exhibiting excellent wood-grain cell structure and concentric growth ring definition.

Regional Reference Suite: additional documented ore and rock-forming mineral specimens including

Actinolite (Fort Spokane, WA),
Bornite on Quartz (Baltic Mine, Painesdale, MI),
Bornite & Quartz (Tic Mine),
Fossil Fern Impression
various metallic sulfide matrices from the Coeur d'Alene district.

Specimen sizes range from small thumbnail reference pieces to medium/large cabinet display specimens (up to approx. 5–6 inches).An invaluable acquisition opportunity for collectors specializing in historic mining lore, Pacific Northwest mineralogy, or antique scientific provenance
