Design eras

Baseball jersey eras track the league's official suppliers: Rawlings through much of the older period, Majestic from the 2000s, and Nike from 2020 onward. Within each era, jersey tagging and the jock tag at the hem are the most reliable dating tools.

Toronto's design history runs from the split-tail powder blue of the early years through the championship-era blue-and-white to the modern sets, while the Montreal Expos' tricolour cap and powder blue road uniform remain among the most collectible non-active designs in North American sport.

Baseball also has the clearest tier split of any league: on-field flannels and modern authentic cuts versus replica jerseys with printed lettering. Check whether the lettering and numbers are sewn twill before you accept an authentic price.
