Great input everyone...
I also have rhodes with the "marking" on the side...
The "30" are sheet numbers....there are a few rare examples out there that clearly show it is the top half of "30"(ther is a cobb red port with it clearly "30" visible)...
i have only seen them on sweet cap backs(sheet numbers)....
THE 25's ARE SUPER RARE.....
i would like one.....i have a few "30"s , but no "25" sheet numbers....ANYONE HAVE ONE FOR SALE??
sheet numbers are rare to aquire, but the 25's are the real rare ones....
