AT my local Ginos a large one topping is $9.98
Even at that price it would come to $160.00 plus tax for 16 pizzas.
“Average”
There are a LOT of small pizzerias doing good business selling >$30 pies (and we’re talking as small as 12”).
My local favorite prices their 18” at just over $30 for 5 toppings for that combo.
Example for Portland area 12” pie pricing:

(NOT a place I’d ever dine, but specialty pizzas have found their niche)
