Very early E.I. du Pont de Nemours & Co. blasting caps tin, marked “XXXXX Blasting Caps”, representing an older grading system used before standardized numbering (such as No. 6) became common.
This example stands out with its simple, embossed lid design and lack of colorful lithography—an indicator of an earlier production period. Pieces like this are often associated with late 19th to very early 20th century mining and industrial use.
Condition:
Authentic, untouched antique condition:
→ Heavy patina and oxidation throughout
→ Surface corrosion consistent with age and storage
→ Embossed lettering still visible and readable
→ Solid structure with strong relic character
Approximate Size:
~3 inches diameter (see ruler in photo for reference)
Historical Significance:
Before modern labeling systems, blasting caps were often graded using “X” strength markings. This makes examples like this particularly desirable, as they represent an earlier phase of explosive manufacturing history tied to early mining expansion and frontier industry.
Why this piece is special:
→ Early “XXXXX” strength marking (less commonly seen)
→ Primitive, embossed-only design (no lithograph)
→ Strong aged patina with authentic relic appeal
→ Likely older than most standard numbered tins
Perfect for:
→ Advanced mining relic collectors
→ Early industrial / frontier-era collections
→ Display alongside higher-grade lithographed tins for contrast
→ Authentic Western / gold rush artifacts
A true early piece of American mining history with strong character and collector appeal.
