what us coins are 90 percent silver

[SanMiguel]

Of course! I can certainly help you with that.

Generally, most United States dimes, quarters, half dollars, and dollar coins that were minted for circulation in 1964 or earlier are composed of 90 percent silver. This is the simple rule of thumb that collectors and investors often use.

To get a bit more specific, this includes several well-known coins. For dimes, you have the Roosevelt dimes (1946-1964) and the Mercury dimes (1916-1945). For quarters, the Washington quarters (1932-1964) and Standing Liberty quarters (1916-1930) are 90% silver. With half dollars, you're looking for the 1964 Kennedy half dollar, Franklin half dollars (1948-1963), and Walking Liberty half dollars (1916-1947). The classic Morgan (1878-1921) and Peace (1921-1935) silver dollars are also in this group.

The provided search results use the term "junk silver," which is a common phrase in the industry. It sounds a little negative, but it simply refers to these common 90% silver coins whose value is based on their silver metal content rather than any special rarity or collector (numismatic) value. After 1964, the U.S. Mint largely stopped using silver in its circulating coins, which is why that date is such a key cutoff.
