My current project is to get my collection to contain 100 unique players for each of the teams in the North American Big 4 leagues.
For this, it is also a prod to further complete my collection entry into the database. For hockey, since it is my primary focus, I am already likely there for all team except the Golden Knights and Kraken who likely don't have 100 unique players on cards yet. For baseball, I am likely close, in particular once I get my backlog entered.
Football and basketball being lesser focus collections for me, I doubt I've accomplished it for any team.
Status of teams completed:
Baseball - Atlanta Braves, Baltimore Orioles, New York Yankees, Toronto Blue Jays (all before starting this post), Oakland Athletics (2023-01-08), Los Angeles Dodgers (2023-01-08)
Basketball - none
Football - none
Hockey - Boston Bruins, Buffalo Sabres, Calgary Flames, Chicago Blackhawks, Detroit Red Wings, Edmonton Oilers, Los Angeles Kings, Montreal Canadiens, New Jersey Devils, New York Islanders, New York Rangers, Toronto Maple Leafs (all before starting this post)
This morning I logged my 100th unique San Diego Padres player as I work on that team's outstanding cards. It was this lovely junk wax era specimen : 1988 Donruss Stan Jefferson
