Hi althoshakir,
Welcome to the Apple community, where some of us do our best to help each other.
I think this is something you would need to find out from Apple.
You'd need to find out the year and Operating System of your old MacBook Pro to tell them.
(You can find this info. from "About this Mac" (Apple icon, left.on top menu bar)
Apple has a page online about Trade-ins:
(To get an estimate, you' need to scroll down below the iPhone info to select "computer")
https://www.apple.com/shop/trade-in
If you still need more info:
You can click on the link "Contact Apple for support and service" at the top left of this page.
All the best
