This was purchased at a magic shop 10 years ago. It's a flipper coin!! It's a rare version in Japan. A 5 flipper coin is a gimmick coin used for coin magic using coins. It can produce amazing effects such as coins splitting, disappearing, and teleporting. In particular, the phenomenon of a coin changing from two to one is famous. The design is such that it doesn't look out of place even when viewed up close, making it safe for close-up magic. Basic Usage (Routine Example) 1. Show two coins Show that you are holding one coin in each hand. In reality, one is a flipper coin and the other is a regular coin. 2. Gather in one hand Gather the two coins in one hand. The moment you close your hand, the flipper coin automatically closes and appears as one coin. 3. Change to one coin Slowly open your hand, and the two coins have become one. Show that there is no coin in the other hand, and surprise the audience. There are no explanation videos. It cannot be used as real money. It's an old coin, so there is rust.
