iPhone 11 Pro gift card trade-in value?

I have an iPhone 11 Pro in perfect condition that I wanted to trade in for an Apple gift card. I wanted to do this before the iPhone 12 came out because I can guess that the value will decrease by then. Looking at Apple’s trade in website, it doesn’t list the iPhone 11, 11 Pro, or 11 Pro Max. What are the current trade-in values for these phones?
