However, its value is substantially higher if it is rare or collectible.

The silver quarter was last minted in 1964. Read more about what United States quarters are made of 90% silver.

How to Identify a Rare Silver Quarter

There are a handful of features to help identify a rare quarter.

First of all, it's essential to look at the general design. Is there a portrait of George Washington on one side? If not, your coin is undoubtedly uncommon and collectible.

Next, check the year-date on the coin. This will usually be the most obvious sign of its rarity. In general (but not always), the older the coin is, the more valuable it will be. All quarters minted in 1964 or earlier are composed of 90% silver.

You will also want to locate the mintmark. This small letter is usually found on the reverse of the coin near the bottom of the design. It indicates which branch of the U.S. Mint made the coin. (No mintmark means the coin comes from the Philadelphia Mint.) Another general rule is, quarters with a mintmark are more scarce. Thus this makes them more collectible.

It's worth investigating whether or not your coin is a unique variety or error. You can consult guide books and online resources to compare your coins against them. Varieties and error coins are much more valuable than their "normal" counterparts.

Sell Your Silver Quarters

Silver quarters are in relatively high demand if you choose to sell your coins.

If the quarters are in particularly good condition, you may consider getting them professionally graded. Many collectors prefer to buy coins that are already graded by NGC or PCGS.

It's also reasonable to sell your silver quarters together as a lot, rather than individually, if they're in worn condition.

Gainesville Coins proudly has 90% silver quarters for sale in bank rolls of 40 quarters each. The rolls are often a mix of Washington, Standing Liberty, and Barber designs.
