For example, the SR signature card at the beginning of P20 represents a 2020 limited card (P-20, corresponding to 2020), with the number GP in the lower right corner and the silver Aote signature on the card surface.
SSR signature card is also a miracle version of exclusive signature card. SSR signature card has only gold Ott signature on the card surface, which is not rare and has average collection value. SGR signature card comes from the SGR signature card of Altman hero duel series. The card face is signed in hot stamping Otto language, and the yield of the card is relatively low, which has certain collection value.
