Yes, you can get cash for traveler's checks.

You can cash your traveler's checks at certain banks. To find a bank that will cash your traveler's check, you can check the website of the group that issued your traveler's check. American Express lists national and international banks that will cash traveler's checks. If you cannot find the banks online or if you are unable to go online, you can call the customer service number that is on your checks.

What Happens If Your Traveler's Checks Are Lost or Stolen?

If traveler's checks are stolen, they can be either replaced or refunded as long as you have the serial numbers of the checks that were stolen. It is also helpful to have the date and location where the traveler's checks were originally purchased. Some institutions require that an official police report be filed before they will issue replacements. Once that is complete, call the number that was given by the issuing financial institution. Checks are usually replaced within 24 hours.
