Across
  1. 2. Method that inspects fields, lettering, and reeded edges under a jeweler's loupe or stereo microscope
  2. 4. Coins made to imitate the real thing and used for gain
  3. 6. Testing method that measures how fast sound waves travel through metal using an ultrasonic transducer and coupling gel
  4. 8. Branch of metallurgy that involves the study of the microstructure if metal and alloys
  5. 13. Black stone used in destructive testing across which a coin is rubbed to leave a metal streak before applying acid
  6. 14. The acient greek word for "metal" or "mine"
  7. 15. Physical method that weighs a dry coin and suspends it in a cup of distilled water to measure displaced water weight
  8. 17. Destructive chemical method that rubs a coin across a black touchstone and applies testing solution
  9. 19. Type of forensic metallurgy examination that determines type, composition, and characteristics of materials to help identify iron, steel or aluminum
  10. 20. Testing method that applies indenter loads and analyzes fracture faces using a scanning electron microscope to determine tensile strength
Down
  1. 1. Testing method that taps a coin with a wooden stick or another coin to analyze its sound frequency using a smartphone app
  2. 3. Testing method that places a coin onto sensor wand to send electromagnetic waves deep into the metal and test resistivity
  3. 5. Examination of damaged metallic materials to determine why they broke, cracked, or deformed due to stress or corrosion
  4. 7. Forensic examination type that determines whether two or more broken metal pieces physically fit together along their fracture surfaces
  5. 9. The science and engineering of extracting metals from ores and manipulating atomic structures to engineer resilient alloys
  6. 10. Fluid used to restore tampered serial numbers
  7. 11. Forensic examination type that involves examining two or more metallic samples to determine physical and chemical similarities and differences
  8. 12. Non-destructive testing method that bombards a coin's surface with x-rays inside an analyzer to display exact elemental composition
  9. 16. Coins made in molds to imitate the real thing
  10. 18. coins made by a striking or stamping method
