D304 & Back Scarcity Update 4/2017

[Leon]

A project in the making is cleaning up and revising our Net54Baseball Archive Center on the forum. It is under the little icon right above here, and 2nd from the right in the row of them and looks like a file folder.
The D304 back rarity thread there now, and many other of the reference links, are from more than 10 yrs ago. Boy, how time flies when you're having fun! On with the show to update them and add some new ones.

The D304s come with 5 different backs.

Brunners
Fleischmanns - Butter Crust
General Baking
Martens
Weber

The Martens and Weber's backs were easily considered the toughest, at least from what I remember, from 15-20 yrs ago. I know it took me the longest to find a Martens and it wasn't even listed in the big Krause SCD back then. There have been some groups of Martens and Weber's found in the last few/several years which probably narrowed the gap somewhat. I see more Brunners than the others, but after that it gets pretty close. Any other opinions on the back scarcity (or even player scarcity for that matter) of our beloved D304s?
And on that last subject, as far as players scarcity, Tenney used to be considered the toughest but it seems the collectors doing the set have him. His prices and value have come down and *almost fallen to other common player prices. Cobby seems to be going up in value a bit nowadays.
My lonely D304 miscut back from the original collection. Rucker wasn't gone long and is actually quite a scarce miscut for the series.
