I know this isn’t sports related, but its just too cool. Funko’s line of Pop! vinyl figures have grown in popularity over the years. Comic-Con and Loot Crate exclusives can command serious money on the secondary market. Starting last fall they began making pins based on some of their most popular figures. They aren’t rare, and can easily be purchased for a couple of bucks.
Funko needs to make more sports figures. They have some, but not a lot. Characters from television and movies seem to get the Pop! treatment more often. The San Francisco Giants had a Toy Story Pop! figure they gave away in 2014. I’d like to see more teams give out exclusive Pop! figures as stadium giveaways. The most valuable sports themed Pop! figure I believe is the Seattle Seahawks Freddy Funko one that was available during San Diego Comic-Con last year. I could be wrong though. Those can sell for $100-$135. Sometimes prototypes can find their way out and go for a lot too.
