MANSFIELD (CBS) – A counterfeit $100 bill was good enough to fool workers at Shaw’s supermarket and good enough to pass the marker test, but detectives determined it was fake after finding a couple of subtle discrepancies.

Police say someone walked into the market back on February 18 and bought a small bag of Doritos, Dentyne Gum, and two 16 oz Cokes. The bill came to $6.52.

Police describe the suspect as a thin built white or Hispanic male with chin strap facial hair. He was wearing a dark colored hooded sweatshirt, a dark colored baseball hat with a gray visor with a large sticker on it.

There was a large emblem on the front of the hat but police aren’t certain what that emblem depicts.
