Just out of interest Ady, what numbers of a run did you do for each ani single? Seem to remember reading the 100 has a capacity of around 300, so was it around that? whatever the numbers, have you any idea why some seem to be 'rarer' than others, maybe in the early day people put them under a chair and forgot to take them home, or maybe trashed them becasue they didn't think they be collectable?
