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've seen it on BH, specially on the stars. Fatigued die?

    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.

    Experience the World through Numismatics...it's more than you can imagine.
