Do you recognize this early 'Photograde' image from a publication?
I recently bought 6 photograding photos dated to the 1950s (or thereabouts), and I'm attaching an example of the Indian Cents photo. I've never seen anything like these before, but really like them. I'm assuming they were used in some numismatic publication, but I have not found that publication (if any). I suppose they could be privately made, but again I don't know. I tentatively found two earlier photograde publications where these may have been published, but I don't own copies of those books to confirm.
- A guide to the Grading of United States Coins, by Martin R. Brown (1964)
- New Photograde - A Photographic Grading Guide for UNITED STATES COINS, by James F. Ruddy (1970; there may be earlier versions)
If you recognize a matching image from one of these 2 publications or even a different publication, I'd really appreciate knowing where these come from (if anywhere).
