WELL WHEN IT COMES TO COCA-COLA BUTTON SIGNS FOR EXAMPLE, ALLAN PETRETTI AUTHOR OF THE C-C COLLECTIBLES PRICE GUIDES PUBLISHED FOR SEVERAL DECADES HAS ALWAYS LISTED PORCELAIN VERSIONS MORE VALUABLE THAN THEIR TIN COUSINS. I COULD NEVER FIGURE THIS OUT SINCE PORC VERSIONS LASTED FOR MANY YEARS AND TIN ONES GOT WORN AND FADED IN SHORT ORDER. I SHOULD THINK THAT TIN SIGNS WERE THE TRUE SURVIVORS HERE WHETHER HUNG OUTSIDE OR INSIDE....MANY TIN SIGNS WERE THROWN AWAY, REPAINTED FOR SOMETHING ELSE OR JUST BUTCHERED AND PLACED IN A LOCATION MOST OF THE TIME THAT WOULD RUIN THEIR ORIGINAL VALUE. I'VE HEARD STORIES OF HOW THE PORC BUTTONS WERE USED FOR SLEDDING DOWN HILLS AND MIXING CEMENT IN TOO....BUT I BET THEY WERE STILL FAIRLY GOOD IF NOT TOTALLY ABUSED. LOL!
