JEFFERSON CITY, Mo. (AP) — Missouri’s treasurer wants residents to keep their expired gift cards because they never really expire and could end up as unclaimed property.

State Treasurer Clint Zweifel says he has nearly $6.2 million in unclaimed property consisting of unused gift cards and certificates. Zweifel also says his office has returned more than $107,000 from expired cards.

Zweifel says people who think a gift card has become unclaimed property should first check with the business where it was bought to see it’s redeemable. If it’s not, he suggests people search for their names in Missouri’s unclaimed property database.
