The code in the lower right corner of the Ultraman card is used to identify the authenticity of the card. The specific coding types are as follows:

1. Smell the card, the smelly one is fake Card.

2. Count the stars on the monster or Ultraman. Genuine cards can have up to 10 stars. There are 6 stars, 8 stars, and 10 stars. Those with more than 10 stars are fake cards.

3. Look at the flatness around the card. The fake card is rough around the edges and the trimmed edges are uneven.

Please note that these methods are only suitable for identifying the authenticity of cards. For the evaluation of other aspects such as the rarity and collection value of cards, you need to refer to other relevant information.
