Annual Probability of Finding Significant Money

Surveys suggest that approximately 10% of Americans find some amount of money on the ground in a given year, though the vast majority of finds are small amounts (coins and occasionally small bills). Finding $20 or more is much rarer, estimated at about 1-2% of people per year. Finding $100 or more is extremely uncommon.

Americans lose a remarkable amount of currency each year. The Treasury Department estimates that about $48 billion in US currency is "lost" (not in circulation and not in bank deposits), much of it literally lost in couches, laundry, car seats, and on the ground. Coin-counting machines at grocery stores process over $3 billion in loose change per year. About 2% of coins produced by the US Mint each year are lost permanently.

Legal requirements for found money vary by jurisdiction. Most states require finders to make reasonable efforts to find the owner for amounts above a threshold (typically $25-$250). Unclaimed found money must usually be turned over to police. After a waiting period (typically 30-90 days), the finder may be entitled to keep the money if no owner claims it. Cash found in businesses belongs to the business, not the finder.
