I recently bought digital copies of The Roman Imperial Coinage.
The scans are great and I've already found the book to be very helpful, but unfortunately the copy is missing two pages. Coincidentally I have two coins that would be on these two pages, so I can't confirm my attributions.
In Volume II I'm missing:
Page 218 (Anonymous Quadrans 19-28)
Page 281 (Trajan 510-530)
Can anyone help me out? Maybe send me pics or scans of these two pages?
