This is a misperception. Cards printed on Sheet A* and B* will have a bold 40th Anniversary logo. Approx. 1 out of 3 DS cards will look like this.

When Topps switched to making DS cards some time during their 1991 print run, they switched to using a red ink that includes a brightener. This ink will flouresce under UV light and is a method for eliminating non-DS cards. Both cards printed with the bold red logo and the watermarked version (ie faint version on sheets C-F) will have flourescing logos. It has been discussed in previous posts that a significant majority (99.6%+) of DS cards were printed in this manner - so it is a good way to eliminate non-DS cards. To summarize, shine a black light on the reverse of the card. If the 40th Anniversary logo (bold or otherwise) doesn't flouresce - it is likely not a DS card.

I don't want to hijack the original thread. If anyone wants more info with pics and specific examples PM me and I can start a new thread with all the info., including other things I have learned since the original discussion.
