The racket is like a mobile phone, it is being updated step by step with the development of the times! Times are developing, and technology is also advancing. Badminton rackets have evolved from the earliest wooden handles to the current carbon fiber ones. The evolution from heavy rackets to lightweight rackets, including the performance of rackets, is also innovating with people's requirements. Unless it is a racket with collectible value (such as a celebrity racket, Lin Dan's signed collector's edition), it will not be very valuable!
