Gi is the backup jersey for the game, that is, the jersey hanging in the team locker room. Subscripts are generally marked with season and year, and prices are generally 1000 to 2000 or 2000+
GU is the jersey worn by players and has the highest collection value.
MN seems to be a mini version of the jersey, and the price is similar to that of ordinary jerseys, but I'm not sure about this, for reference only ~
I can tell you something else.
Rep is an offset printing plate, which is printed with numbers and names, which is the kind that Ad sells 398. The replica version of NBA jerseys, commonly known as replica jerseys, is the cheapest jerseys in specialty stores.
SW is an embroidered fan version, with embroidered numbers and names. The jerseys are generally mesh, and Adi sells for 580.
Hope to adopt, thank you!
