Very tough to find. Black and white reprints of a late Golden Age US comic book title published by Wanted Comic Group and lasting 41 issues from 1948 to 1951.
There is very little sales data in the UK to arrive at values but rest assured they are extremely scarce, even rare in circulation. I note that a #13 mid grade copy sold on eBay UK for £6.99 in Jun 2023.
Grade and market demand equals value so at this point it is a case of worth being whatever someone is prepared to pay for an issue when they see it!
Note: some PR issues may have no value. Selected issues in FN, VF or VF/NM may not exist in some titles.
