Hi, I recently pruchased the speciman below. It is a 1922 Peace dollar. You can see, that the coin is struck slightly off-center. Initially, I was suspicious. However, it weighs 26,73 grams and sounds like silver. Any ideas?   |

 to CCF. Could be a minor MAD. Looks like a D mint mark.Also looks a bit to shinny. Check with a magnet,let us know if it sticks. John1  |

Hello John, thank you a lot for your comment. I highly appreciate your input. The hint reagrding the potential MAD ist very helpful. Regarding the magnet: the coin does not stick. Hence, weight, ping test and magnet come out right. Do you know of any other alternative to check for authencity, that dooes not harm the coin (like e.g. bleach)?

specific gravity test or XRF. the XRF might be hard to get done, you can google specific gravity test for silver, you should be able to do this at home.

Get a vernier caliper micrometer gauge... less than $10 on ebay. You can then precisely measure any coin diameter and thickness and compare with mint standards. |

This coin looks brightly polished and I wonder if it had been mounted in a bezel as a jewelry piece. I'd examine the edge reeding and rims carefully. The potential MAD error could be post-mint damage.

You can try the tissue test. XRF test would tell for sure. It does kind of look like a former jewelry piece as Jaobler said. John1 |

The coin has been highly polished so it is basically just a little over silver value. The MAD isn't significant.

Are the reeds on the outside edge of the coin? If not, they may have been removed and thus lighten the coin a bit confirming it was a piece of jewelry at one time.

Thank you all for your comments. I appreciate your inputs. I am a relative greenhorn, so I actually did the specific gravity test for the first time ever. It's fun, by the way, my first physical experiment since school :-) It turned out as follows: submerged weight 2.60 grams. As the coin weighs 26,73 grams non-submerged, the ratio is 10,28. It think, this is close enough to pass the test. Please see the photo for reference. I also uploaded a photo of the edge.   |

So, my take home is: most probably a real coin, slight MAD error, value materially decreased by unappropriate cleaning. Does anyone agree or disagree? Once again, many thanks to all you folks and very best regards from Switzerland.

Genuine: Yes Silver: Yes MAD: Yes, but not enough to add value Value: Melt value John1 |

The damage on the rims prevents it from being a high grade/collectable coin.
