I just checked the labels and the bottoms of the tins, and there's no indication of how many were made. The distributor, Diamond Collectibles, might know the answer to your question though.
Thanks, again, for clarifying that the seller was, indeed, Diamond Collectibles. I asked him this question in my email, and he didn't give me an answer ... kbmum provided there information in this thread:
http://www.theyakshack.co.uk/forum/index.php?board=6;action=display;threadid=1838I looked them up on this online phone book though google. I noticed they were in Allentown, and I was gonna give them a call to see if they had the tins. Since I was too busy, I wasn't quite able to get it done. When I BINed the first tin (Knight Bus), I noticed they were also based in Allentown.
Anyways, I'll send them an email when I receive my tins and see what kind of a response I'll get ... I could also contact Artbox. They have been getting much better emailing via their customer service!
