What Magnets Are the Size of Coins?
Our closest coin-size magnets are thin discs: 3/4 × 1/16 Inch for a penny or nickel, 5/8 × 1/16 Inch for a dime, 1 × 1/16 Inch for a quarter, 1 × 1/16 or 1 × 1/8 Inch for a dollar coin, and 1-1/4 × 1/16 or 1-1/4 × 1/8 Inch for a half dollar. None match a coin exactly, but they’re very close.

Don't Put Magnets in Coin Slots or Wallets
Strong magnets can erase magnetic-stripe cards and confuse coin-counting machines. Keep them separate from wallets and coin mechanisms.
