Business owners in Fairfield and surrounding areas are being warned by Fairfield Police to double check money received particularly $100 bills. Restaurant Archie Moore’s , candy store Sweet Rexie’s and most recently Fairfield University Book Store have fallen victim to receiving counterfeit $100 bills. In all instances the bogus bills were received in exchange of a smaller purchase, usually around $10. At this point it appears to be different people passing the funny money. Police are warning merchants double check large bills either by close inspection looking for watermarks on the bill or with a counterfeit detector pen.
