Cents must be the subject of electrolysis students all over the country. The Coin Doc gets lots of questions about silver or gold plated cents. What you have is a plated cent that is commonly used in advertising promotions. Promoters give out gold plated cents because people are attracted to a cent that looks like gold. But there are no gold or silver cents, never were. At 3.11 grams, a cent weighs a tenth of a troy ounce. If the government made them in gold each cent would be worth about $120 at the present gold price!
You can prove that it is really a standard copper and zinc cent by weighing the coin on a gram scale. A standard 1990 cent weighs 2.5 grams. One minted on a gold flan would weigh considerably more than that.
Since gold is so ductile, the value of the plating is nominal. A neat curiosity though!
