The
noise produced by the drophammer’s blow will certainly
attract the attention of costumers and passers-by. In that procedure,
a 42kg weight is lifted up and suddenly dropped down to stamp the
coin. The trick consists of holding the hammer in the air
immediately after the first blow; otherwise the result will be a
faulty coin. The defective coin is for sure unique, but let it be
done by the coinmaker! |
