Probably not if it is the correct weight. It may have been gold plated for some promotion, but if so, the amount of gold would be worth less than the cost of having it removed and assayed for sale. More likely, the coin has been exposed to some chemical which reacted with the copper and caused it to change colors. It is possible that it was minted on a planchet intended for a foreign coin, in which case it may be worth a few dollars.
Chances are, your coin was used in a common chemistry project some time back. In the project, students essentially plate the copper plating of the penny with an addition layer of zinc (only a couple of atoms thick in some cases) and then heat it, mixing the new layer of zinc with the outermost part of the copper plating. This results in a brass coat on the outside of the panny, making it look golden.
sadly their is no addec value so its worth 1 penny
If it is a penny, then it has to be.
It's may have been plated for use in jewelry, or more likely was used in a high-school chemistry experiment. I forget the details but there's a compound (NaOH2 ?) that reacts with copper to turn it a goldish color. Either way it's not worth anything as a rarity but it makes an interesting conversation piece.
The US never made a gold penny. For one thing they'd be worth a lot more than 1 cent! You may have a coin that was plated for use in jewelry, or that was exposed to heat or chemicals that changed its color. There are several different high school chemistry experiments that can produce a goldish tint on a penny.
Anything that costs a penny.
Coke or sprite will change the color of a penny.
copper
1862 penny worth anything
A 1972 US cent would be made of solid bronze and have a different color than a new one, but not goldish. If it sticks to a magnet, it is either not real or has been coated with some metal with magnetic properties.
Regardless of what country it's from, it's worth 1 penny. No country makes gold pennies for circulation because they'd be worth 80 or 90 USD. Your coin was either plated or exposed to a chemical that altered its surface color. There are standard high-school chemistry experiments that react with the copper to produce a goldish tint.
The U.S. has never made a gold penny. After all, if you think about it for a few seconds, what sense would it make to mint a coin worth tens or hundreds of dollars and put it into circulation for 1 cent? Your coin has had one of 3 things happen to it: 1. It was plated for use in jewelry. 2. It was exposed to heat or chemicals that changed its color 3. Its copper coating was put on near the end of the useful life of the particular batch of copper. The copper had become contaminated with zinc from the many uncoated coins that came before, which lightened its color. Regardless, it's only worth a penny.
It changes from the golden color back to a grey color.
