1949-D Jefferson Error... Help!... Very Cool

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.

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.
