Frequently Asked Questions

Why is a dime smaller than a penny or nickel?

Dimes were originally made of silver (more valuable), so they could be smaller while maintaining value. Pennies and nickels were made of less valuable metals, requiring larger size. Even though dimes are no longer silver, the size remained.

How many dimes are in $100?

$100 = 1,000 dimes. That's 20 standard coin rolls of dimes.

What is a dime worth in other coins?

1 dime = 10 pennies, or 2 nickels. Two dimes plus a nickel = 1 quarter (25¢). You need 2.5 dimes to equal one quarter.

How much does a dime weigh?

A modern US dime weighs 2.268 grams (0.08 oz). 50 dimes (one roll = $5) weigh about 113 grams (¼ pound).

Are old dimes worth more than 10 cents?

Yes! Dimes minted before 1965 are 90% silver and worth more than face value (currently $1.50-$3+ depending on silver prices). Check the edge—silver dimes have no copper stripe.
