Here is a pricing situation that should not exist.
A jersey for a current player, on a current team, costs a certain amount.
A jersey for a player who retired three decades ago, on a team that may have moved or changed its name, costs considerably more.
The old one has no current relevance. The player is not playing. Some of these teams do not exist.
And yet the price is higher, people pay it willingly, and a Philadelphia company built a business on exactly this.
The explanation is that the two items are not the same product. One is fan merchandise. The other is a piece of someone's past, and those are priced very differently.
