Thanks for letting me know, i removed #183. I see another double also, but that has #223 at the cover, oh well i will sort it all out when ik reorganize the pages again.

Alan Class would sometimes use the same contents from one issue of a title in a later issue of the same title. I think there is a THUMDER Agents cover that is used at least four times. I have a later issue but was able to compare its contents to the earliest one and found the two issues were identical.

I have four copies from the 70’s 80’s, 1 Secrets Of The Unknown, 1 Sinister Tales, 2 Creepy Worlds, any idea if they are worth anything?

I see that you’ve been adding new Secrets of the Unknown scans every month. Where are you getting these scans? Another website? Your own collection? Is someone sending them to you anonymously?

I find/get everything from different people and sites, some are private so i can’t go into details.

In your latest update you’re missing #102, but #238 has the same cover as #102 and may also have the same contents. comics.org has a cover scan for #238 but does not list the contents. https://www.comics.org/issue/332986/ Does your anonymous source have Secrets of the Unknown #238?

Thanks, i will look at the coverissue. I don’t know if he has that issue. It will all become clear when i have all issues and reorganize the page.
