Atwood Coffee Catalogue [solved]

On the following reference catalogues

AC

AC7

AC8

These 3 references are a continuation of the same with the same reference numbers in all three. Each book is complete with all prior catalogue numbers each time. Each edition has errors removed and new items are added in with the rest of the catalogue. Even though AC - Catalogue 1-6 and AC7, AC8 are compiled by different authors, it is essentially the same catalogue.

Hi,

I the various editions share the same reference numbers, they should indeed share the same code.
I removed AC7 and AC8 and assigned the code AC to the whole group: https://en.numista.com/literature/volume_group.php?id=714

AC8 is still listed in the reference catalogs separate from AC reference.

Sorry I missed that. AC8 is now removed.
