Jay MillerFrank--I collect these and would divide the backs into four scarcity categories(my opinion as to scarcity--others may disagree):
Common--SN, Blank, Famous & Barr, Herpolsheimer
Semi-Tough--Altoona Tribune, Gimbels, Globe, Standard Biscuit, Successful Farming, Wares, Weil
Scarce--Block & Kuhl, Burgess Nash, Green Joyce, Indianapolis Brewing, Morehouse Baking
Rare--Everybody's, Mall Theatre, Holmes to Homes
It should be noted that there are varieties of many backs. There are three different Gimbels backs and several, including Standard Biscuit, come with inverted backs.
I can send scans of most if you need them. Also, if anyone comes up with an extra Holmes to Homes (I sold mine to Leon years ago) please contact me.
Good Luck--Jay
