The 2006 Scott’s Specialized Catalogue lists the following, with some prices being given:
57 e 1d. rose redwmk and Q (68) vertical pair, imperforate horizontally $725 used
58 e 2d. gray blue wmk and Q (68) imperforate horizontally $1,100 mint
60 a 6d yellow green wmk and Q (68) imperforate
Also a note that says"Nos. 59-60 exist imperf. vertically"
Robson Lowe (1962) notes the following all known imperforate vertically between pairs
62 1d reddish-brown Die 1 £6 used
63 1d reddish-brown Die 1 £7 used
67, 70, 71 listed but no price as "unknown to us." I assume that means they are aware of these stamps existing but have not seen them.
Going back through the historical record I find the following:
The 1912 Stanley Gibbons lists no imperforate copies.
The 1940 Scott’s Standard Postage Catalogue lists the following, without any prices being given:
