I have (2) 72" diameter Gulf porcelain signs that are not a matched pair and the font of the letters is different

I'm trying to determine if one is more desirable than the other

The one already mounted on the wall seems a more vibrant orange, but has more actual rust and damage, I cleaned it with soap and water
The one not mounted, I just pulled out of the woods, its been laying flat for 30+ years. I also cleaned with soap and water and a nylon brush but its not as vibrant and has a different font but is also has less damage and rust

I inherited both of these with the family farm and want to gift one to a relative and am trying to determine which one i should keep and witch one to gift

Dollar value is always good to know but from the font is there a way to know if one is older? or honestly s older better ?
What makes one mor desirable than another, I guess is a good place to start

Thanks for the assistance, opinions and information

Tim
