Is there anything unique to the 1963 Ford Galaxie Door panels to determine if original part

[mlt74]

Recently became the keeper of two front door panels and two rear door interior panels. They are in amazing shape. One has some small defects but really - they are so awesome that I want to just hang them for display. But they deserve to be enjoyed and have some life. I didn't know the previous owner. He has 1963 Ford Galaxie 500 written on the back of one panel. I am running with that as accurate. I'm trying to figure out though how I would know if this is the original or a reproduction. Would there be any distinguishing marks or anything that would help me out.  I'm a rookie to all of this. Figured I would come to the land of many experts.
