Detective Comics #25 worth

The item you're asking about, Detective Comics #25 (1939), is listed as being worth $1,434 used [1]. This is the original and most valuable issue of Detective Comics #25, famously featuring the first appearance of Batman.

The other items listed are later reprints or different issues in the series and are significantly less valuable. For example, Detective Comics #25 (2014) is only worth $2.55 used [2], and the other items are from 1958 and have values ranging from $67 to $95 [3-8].

If you have the 1939 version, it is a highly valuable collectible. If you have a different version, let me know, and I can provide more specific details.
