There’s just something strange about a gold penny. First of all, gold pennies don’t exist… unless you’re a 20th-century alchemist who knows something about the science of alloys. Modern day alchemists, cleverly disguised as chemistry teachers, often share the secret of making gold pennies. Students take home an unforgettable lesson in alloys and a keepsake penny that can never be put back into circulation – even though it’s a “gold” penny, the US Treasury has a little problem with people buying something with gold pennies.
