A reserve fee for your jersey auction, probably.

Reserve price
Minimum price that must be met for your item to sell

 $5.00 or 7.5% of reserve price, whichever is greater (maximum fee $250)

You listed an item with a Reserve Price and a sub-title

They are Advanced Listing Upgrades and come with a fee.

$5.00 or 7.5% (whichever is greater) for the Reserve = $7.50

$1.50 for the Sub-title
