Thanks to new member Liz for posting this interesting coin and for allowing use of her photos.
Rippled Coin: This is a form of post-strike damage that causes a doubling (or multiple) effect on the devices. Just as the name suggests, the coin exhibits ripples on its surface, often following the contours of the devices giving them a doubled/tripled/quadrupled appearance. The exact cause(s) are unknown, but contact with an acidic substance is one theory. Photos courtesy of forum member Liz.

Also, I thought I had this entry already in there, but I did not. We see these posted fairly frequently, so I made an entry for it:
Struck Through Late Stage Die Cap This is a coin that was struck by a capped die which has already struck many other coins. The face of the die cap gets thinner and thinner with each strike, as it expands outward. After striking so many additional planchets, the face of the die cap will be thin enough to allow parts of the normal die design to appear on the struck planchets, yielding a ghost-like image of the bust and other devices. As the die cap continues to strike coins, more and more of the normal design elements will show on the struck coins until the die cap completely deteriorates away.
