Have you ever heard the term “Junk” Silver? That’s the commonly used name for US coins that were produced back when Uncle Sam had some integrity, and put real silver in our dimes, quarters, half dollars, etc. Well, it’s not junk and for a couple reasons.
Any dime, quarter, or half dollar minted before 1965 is 90% silver, and 10% copper. Then after the coinage act, 1965 – 70 minted coins only had 40% silver. After that? Now that’s true junk. Our coins are a mix of base metals, but nothing precious in them. They’re only “worth” what Uncle Sam says they are.
