Making Cents of Math: Linear Relationship between Weight and Quantity

Figure from experiment 4 from Forensics with Vernier


NEW THETFORDSHIRE, March 10: Coin collector Clark Esposito thought it was his lucky day when a stranger entered his shop with a plastic sleeve full of rare, mint 1877 indian head pennies. The seller, Zeus Duncan, said he had kept the coins in a locked safe since they were given to him by his father 20 years ago. However, Mr. Esposito’s lucky day soon turned into a lucky break for police investigating a counterfeiting ring operating in the city.
