Wrinkling or stretch marks on a coin

What causes a modern clad coin to have stretch marks or wrinkling across surface?

    Hard to say exactly what you mean without a picture, but for what I THINK you mean: A worn die is usually the explanation. Over time, the movement of metal-against-metal causes creases in the die that are transferred onto subsequent coins struck.

    Often, particularly with large cents, you might hear this called the "Orange Peal" affect.

    When a die ages, "flow lines" start to appear. The devices start to gravitate towards the rim. Those "flow lines" are what I assume you mean by "wrinkling".

    LOL....I knew there was a better word than the "wrinking" I used. ;) Flow Lines is the right way to describe it.

    It can be quite dramatic sometimes on Bust Halves, Large Cents, and the like

    I can only imaging he's talking about the flow lines.

    Best definition I could find:

    Microscopic striations in a coin's surface caused by the movement of metal under striking pressures.

    @Gunnr88 .... Welcome aboard.... without a picture to be certain, the above explanations are reasonable, and likely accurate. Cheers, RickO

    In the 1980s on nickels in particular, die erosion showed as an "orange peel" effect.
