Hello,
I found a gold coin today in my wallet. It is a Dime dated 1991d . The gold on it looks perfect and the dime is slightly lighter then a regular dime. It is also a little bit thicker. Not sure if its gold plated or what but it is cool looking. Any idea what this is and if its worth anything? I'm guessing its novelty item from somewhere but it certainly is interesting.

Yes its most likely a novelty item. I have seen tons of gold plated quarters but never a dime. Could you upload a pic?

I also for some reason test it with a magnet off the fridge and the regular dimes dont stick to it but this one will stick for a few seconds then fall off

Interesting, must be plated with something. Give it a few, I'm sure the experts will chime in.

My daughter just found a dime that looks almost exactly like yours, only hers is dated 1988d. Very shiny bright gold, looks like new, detail is perfect, lightweight. I've never seen one before. Pretty neat even if it's only a novelty.

To plate in gold it is my understanding that it has to striped than nickle plated and than Gold plating. I am not sure if nickle is magnetic but I think it is. I will stop over my brother-in-laws shop and check in the morning, as he has about 900 pounds of nickle chips at his shop.

I cetainly can't afford gold coins for my collection. I'd rather spend the money on lots of more common types. However, a friend of mine took pity on me and had this German mark gold-plated at his place of work so that I could claim to have at least one "gold" coin in my collection!   |

Any Metal could be made magnetic. In fact one of the strongest magnets is called AlNiCo. And as you can see one of the ingrediants is Nickel. Oddly enough though adding Nickel to Iron in the Steel manufacturing process of Stainless Steels does just the opposite and makes many grades of Stainless Steel NON magnetic. As to those Gold Dimes, more than likely a chemistry class experiment when the professor was not watching. Many are plated with Copper or Brass just to make it appear as Gold. One of the more fun things to do with the 1943 Lincoln Cents too. Only with those they are plated with almost anything on Earth. |

Just carl, Your are correct Nickle in it's pure form in non magnetic. The plating process of using the nickle as an over lay is also correct. So why this coin would stick to a magnet for a few seconds I have know idea.

JBuck, I just stuck a magnet in a bucket of nickle and harder steel chips, that had been machined off a new head stock or a 100 foot lath. They did stick! My brother in law told me if it is mixed with other metals it may be magnetic. But Pure alloy is not magnetic.

As I said almost anything, metal or not, can be made to be magnetic. And Nickel is far from an exception. Nickel is normally not but pending how it is stored, manufactured, processed, mixed with other materials, it could be or not magnetic. When Nickel is added to Steels, pending on the percentages, that steel becomes non magnetic Stainless. Again, one of the strongest, NATURAL magnetic metals is AlNiCo which is Aluminum, Nickel and Cobalt. By itself normally Aluminum is non magnetic. Same with Cobalt. However, due to atomic orientational properties, those three mixed properly together makes one of the strongest magnets. Even subtances like Silicon can be made magnetic. Basically it's the strength of the magnetic attractions that are noticable. So back to that Gold looking coin. It could well be coated or plated with a Copper, Brass, Tinned, Iron, or Nickeled combination. It would be great to know exactly what that is coated or plated with though. |

From approx 1968 to 1999 all typical circulation nickels, dimes and quarters in Canada were composed of .99 pure nickel... http://www.coinscan.com/technical/canasp.htmlI have been pulling out these coins with a magnet for some time... so they are attracted by a magnet but I never really thought of making them into a magnet. So, is raw nickel that is mined in Sudbury attracted by a magnetic? ...probably. edit >>> BTW... The Charlton Guide(the Canadian equiv of The Red Book) and the RCM list these dates as 1.00 Nickel(pure), whereas the link provided lists them as .99 minimum purity. Edited by IBGolden
