Weight of skin ..

Options
Has anyone here started out over 300 pounds and lost over half?
I'm curious as to how much weight can the excess skin weigh? I've
been doing both cardio/strength training so I might weigh more
based on scale vs. measurements but there is excess skin in places.
My final goal might not be realistic by the scale so I thought to ask here
what others found in relation to how much weight excess skin can be?
Thank for your replies ..
