We had a customer who tried to cash $3,000 in counterfeit traveler's checks. The branch manager thought we should file a SAR although it does not meet the $5,000 threshold. Their thing was that we don't know how many other checks they were trying to cash at other banks and that that could total over $5,000. Should we file?

You certainly have the option of filing. But were these checks traveler's checks or cashier's checks?

Sorry, they were traveler's checks
