Not thinking Dryer Coin would leave the flakes around the perimiter. Acid maybe, not sure how extreme heat would affect a nickel. Not talking about flames. Edited by stoneman227

I think as it rolled, the metal pushed over the face of the coin and was then pushed over the remaining devices through circulation.

Bear with my conjecture, to me it's acid. The surface of a nickel can laminate. If acid can affect the lam layers it could take away the surface basically in layers. The upsetting mill when it forms the rim disturbs the layers at the edge and basically bonds them as it compresses them making them stronger thus making them the last to go.
Just conjecture.

It is a Dryer Coin.  Exactly how a Dryer Coin looks like. Increased edge thickness and reduced diameter. Acid dipped coins reduce the thickness and the diameter. PSD. No lamination issue. Just a damaged coin. |

It is nothing more than a Dryer Coin, the rim has been rolled over onto the peripheral devices which is what creates the flaking appearance. |

Shows how malleable the alloy is. The foil actually shaped to the letters instead of cracking off.

My first impression was correct. It is a Dryer Coin, and in fact I don't think it's a 1949 D at all. It has the reverse relief of jefferson's from 1978-1984. Edited by CoinHuntingDrew

It would make sense that it would be a 1979 D, and not anything else. I can tell these reverse strikes simply because of a trained naked eye, lol. There are different reliefs and Monticello has changed drastically since 1938.

Here is one that at first glance looks like your typical " Dryer Coin" but most assuredly is not. Notice that it has the folded-over edge only on the obverse while the reverse displays far greater wear on the devices than the obverse. Since similar coins to the subject coin in this thread have also been found in washing machine water pumps and as the result of being used as media for burnishing in rock tumblers, it's my guess there are even more causes of similar effects. The 197X-D dime shown here could not have been the victim of a commercial dryer since the damage would have been equal to both sides from such a stop-and-go source.  |
