I'm new to collecting game worn baseball jerseys and I have some questions regarding different jersey sets:

When comparing the different sets of same type of jersey (same year, team, style)..


A. Is set #1 worth more and/or have more usage than set #2 usually?

B. Are different sets worn during different periods of the season (like in the NHL) or is set #1 the primarily worn jersey of that style and higher #'d sets are simply backups?

C. Are all sets of a jersey style typically game worn (barring injury, trade, reassignment)?


Many thanks in advance!!
