Metal Coca-Cola & Hires R-J Root Beer signs

Calling all Coke aficionados!

When I was a kid in 1967, I removed these signs from a junked soda fountain dispenser because I thought they were pretty cool. I've been trying to find out how old they are and how much they are worth to a collector. No dates or markings other than in small print "Trade Mark Reg." in the letter "C" on the Coke, and "Reg. U.S. Pat. Off. Made in U.S.A." on Hires.

The machines they were removed from were very old back then, but I don't know how old?? The coke sign measures 3.25 X 6.5 inches and the Hires one is 6 X 7.75 inches.

Anybody have any ideas?? Would be much obliged.
