Copper Washers: The copper content in these washers often ranges from 40% to 70% copper, depending on their specific application and required properties.
2. Comparison to Pennies
Pre-1982 Pennies: These contain 95% copper, making them far more valuable in terms of metal content compared to many commercially available washers.
Post-1982 Pennies: Comprised of 97.5% zinc with a copper plating (2.5% copper).
This makes pre 1982 pennies far more valuable with or without holes.
Also post 1982 pennies are worthless as old time fuse replacements! They would melt immediately.
