1999 Cent Ram Strike

Off center strike with planchet partially cupped. That is how I would describe it.

When a coin is struck with no collar, the metal can sometimes be forced up around the die as it strikes the coin. If that effect completely encircles the coin, the effect is that of a small cup, so to speak in that the edge is raised all around the coin. It also happens that the "cupping" effect can be partial , as it is on this coin. It's just a descriptive term used to describe this type of thing.

You'll see the term cupping used as well when we refer to capped die strikes. That's where the cupping effect actually causes a struck coin to get stuck to a hammer die. It's the first part of what would create a coin known as a brockage.

Oh...to answer the original question..numismatists in countries influenced by British terminology, such as Australia, Canada and Great Britain...this would be called a Ram Strike. It is not common terminology here in the U.S.

Thanks,
