Maker
Unknown mass-producer; likely an industrial packaging manufacturer such as Ball Corporation, Crown Holdings, or Ardagh Group.
Material
Aluminum (Alloy 5182 or 5042). This item contains 0% silver content; it is a non-ferrous industrial metal.
Dimensions
Standard size: Approximately 1 inch (2.5 cm) in length; Weight: Approximately 0.33 grams.
Description
This is a contemporary aluminum beverage can pull-tab. While it possesses a silver-toned metallic luster, it is an industrial fastener rather than a piece of fine metalwork. It represents the pinnacle of 20th-century engineering in terms of mass-production and material efficiency.
Key Features
Signature '8'-shape geometry, central rivet hole, and rolled safety edges.
Material & Composition
Aluminum (Alloy 5182 or 5042). This item contains 0% silver content; it is a non-ferrous industrial metal.
Finish & Decoration
Industrial mill finish with rolled edges. It features a utilitarian matte-silver appearance with no decorative chasing or engraving.
Hallmarks & Stamps
None. There are no precious metal hallmarks, maker's marks, or assay stamps. Some tabs may have small numeric mold-cavity identifiers, though none are visible here.
Construction Details
High-speed precision die-stamped and punched from a continuous coil of aluminum sheet metal.
Functional Features
Leverage-based fulcrum design with a rivet attachment point designed to puncture the score line of a beverage can lid without detaching.
Handle & Grip Details
Finger-loop grip designed for ergonomic lifting; smooth rolled edges to prevent injury to the user.
Craftsmanship Details
Machine-manufactured with extreme tolerances for functionality; lacks the hand-wrought characteristics of artisanal silver.
Authentication Indicators
The lack of hallmarks, the light weight, and the characteristic industrial punching marks identify this as aluminum, not silver.
Origin & Manufacturing
Likely manufactured in a high-volume automated factory in the United States or Europe.
Era & Period
Modern Era (late 20th to 21st century). The Stay-On-Tab was popularized in the mid-1970s to replace the 'pull-tab'.
Age Estimate
Circa 2010-2024; based on the pristine condition and contemporary double-loop design.
Cultural Significance
A symbol of modern consumerism and global recycling efforts. It is one of the most widely manufactured metallic objects in human history.
Condition Notes
Good / Used. The item shows mechanical deformation at the rivet point, indicating it has been detached from its original vessel.
Value Estimate
Negligible intrinsic value; approximately $0.00002 USD based on current scrap aluminum market prices per pound.
Care & Maintenance
No specialized care required. Typically discarded or placed in a commingled recycling bin for aluminum recovery.
Similar Pieces
Pop-tabs, ring-pulls, and church-key openers. Can be confused with 'silver' by novice metal detectorists due to color.
Interesting Facts
The Stay-On-Tab was invented by Daniel F. Cudzik at Reynolds Metals in 1975 to prevent litter and choking hazards associated with the older detachable ring-pulls.
