Tozai Senpu : Unnumbered figure on page 8 of the pdf version of the book
Note:
Tozai Senpu is a unique manuscript book, believed to be a partial Catalogue of the coins owned by Kutsuki Masatsuna. The book is housed in Waseda University Library. https://archive.wul.waseda.ac.jp/kosho/ne04/ne04_02183/ne04_02183.pdf
The rubbing from this book illustrated by Greenbaum (see Reference) appears to show this actual specimen of a Thiệu Phong Thông Bảo from Kutsuki Masatsuna's collection. The evidence for this is the pattern of excess metal on the reverse of the coin which is accurately reproduced in the rubbing. In particular the crescent moon above the hole is reproduced accurately by the hand rubbing preserved in Tozai Senpu.

Note:
This paper demonstrates the identity of some of the rubbings in the Tozai Senpu manuscript catalogue with wood cut images in the published books of Kutsuki Masatsuna. When the reverse side rubbing of Figure 5 is compared with the reverse image of HCR 58269, it is apparent that this coin was used for the rubbing. This is the first case of a coin from the Ashmolean component of Kutsuki Masatsuna's collection being identified with a rubbing from his manuscript catalogue.
