Coin and Paper Money Collecting/dime with copper ring


QUESTION: I have a dime that was minted in what looks like 1992 or 1993, the last number is hard to read because it has a copper rim around it like a penny. How would I find out if it is authentic or if someone did it other than when it was minted?


The normal dimes struck during this period are made of a layered material. The two outer layers are Cu Ni (Copper Nickel), while the center is pure Cu (Copper). Sometimes the way the coins are struck/manufactured, a small amount of copper can appear around the edge of the coin. Without a photo, I can't offer an opinion as to the authenticity of your coin. Altered or damaged coins have no added numismatic value.

Here are some examples of non-errors:

If you live close to a local shop, they should offer an opinion as to it's value and if it is authentic at no charge. Always try and get at least two opinions and try and deal with PNG dealers if possible. If you should decide to sell your items to a dealer, remember they will offer about 50% to 60% of the retail value. Here's a link to find one in your area:

QUESTION: What would be the best way to take or send a picture of it to you, or would there be a dealer or expert in my area, Provo Utah that would know if it is authentic or not?


Ask a follow-up question, and attach a photo. You should be able to attach a picture or image from a digital camera or a saved picture in your computer. Just click on the link for attaching a photo and it should link your computer or camera if attached to your camera. go to your picture file and select the photo you would like to send and it should go through.
