Dimes in the modern era typically contain 91.67% copper and 8.33% nickel, and this composition has been consistent since post-1965. Their history dates back to 1796, when their design closely resembled that of half dimes, progressing through various changes until the Liberty Seated type emerged. It’s worth noting that dimes consistently weigh twice as much as half dimes. In the Seated Liberty era, dimes were predominantly made of 90% silver, reflecting a time when precious metals played a significant role in coinage.
