rarest backs

[darwinbulldog]

For those who haven't read through from the beginning of the thread, what I have been trying to compile here is a list of exceptionally rare backs on ACC-cataloged issues. There have to be fewer than 50 total examples of the type (so a T215 Pirate, for example, is too common) and the total number, whatever it may be, has to comprise less than 1% of the total population of the set (so an E107 with the "Breisch, Williams" stamp is too common).

Here, then, is the updated list with changes in bold. I continue to seek input on this.

D310 Aldon Candy, Pacific Coast Biscuit Co. stamp
E92 Croft’s (red)
E94 Your Out, Close's Oppie Dildock, Three Strikes, Pennant Winners, A Base Hit!, Your Safe! If..., Your Safe! Have..., Home Run!, Oh You Fan!
E98 Old Put
E101 D355*
E121 Kings, Gertenrich
E135 Merchant's
M101-4 Haserot's, Mall Theater, Everybody's type 1, Everybody's type 2, Everybody's type 3, Everybody's type 4
R316 Douglas Park, Morton, Rialto, Community
S74-1 Helmar
T205 Hindu, Drum
T206 Old Mill (brown), Lenox (brown), Cobb**
T207 Red Cross
T209-2 B.E. Thompson
T213-3 Factory 8 overprint
W461 Playland
W502/F50 Greiner's
W514 Hendler's, Barker, Mother's, Robinson
W515 Fleer, Jersey

W551 Wool's
W554 Lucky Yo-Yo, Lukcy Deal, 40 Winners, Bonemery

W575-1 Johnson, Henry Johnson green, Henry Johnson and Howard P Bo***, Haffner's, Clark's, Gassler's, Leader Theatre, Queen City, Shotwell, Service Candy, Witmor horizontal, Witmor vertical


*The Niagara Baking back is certainly rare enough to qualify, but Burdick classified it as its own set; so you could say of these cards either that 100% of D355s have the same back ad or that < 1% of E101s are found with the Niagara stamp.
**The T206 Ty Cobb back is included in the list only because Burdick called it a T206. The card would not otherwise be considered a T206, but then again, nothing would, now would it?

if one is looking for an e97 blank back for a type...it is not hard to find one. If one is looking for a particular player...that can be a challenge.

There are no e97 blanks banks that are anywhere near unique.

[Bigb13]

The proofs are not rare? With only one showing in PSA?

[ullmandds]

think what u want...you have a history of overvaluing your cards.

they are not proofs and they are not that rare.

a) I don't know if there are fewer than 50 of them, but
b) I don't think they actually are E97s, and
c) I'm excluding all blank backs from the list anyway.
