Help ID a few coverless books (Action & Sensation) 0

[Kreton]

I picked up a small collection of mostly remainders/returns missing the top portion of the cover and a few coverless books and could use some help identifying a few issues.  The books are as follows:

[Mutant Manatee]

"When Stars Collide!" = Action Comics #63  August 1943

"The Terrible Toyman" = Action Comics #64  September 1943

"The Menace of the Blue Seal Gang" = Sensation Comics #72  December 1947

[Mutant Manatee]

p.s.  The Grand Comics Database is your friend when trying to ID coverless comics.  The easiest way is to search by story title.

Many thanks.  I will check that out.
