I doubt it personally because it's already high priced due to Croc.
Doesn't seem too high priced to me and Croc definitely seems a lesser character than Jason (to me anyhow).
Batman 356 goes for about $6-8 in NM, 358 about $20-30 (again, because of Croc), 357 you are lucky to get under $50 for a decent grade raw. "high price" is all relative to each person, but that specific issue is a lot more valuable than the other issues around it.
Off the top of my head I can't think of any issues that have two major first appearances in it to compare on price inflation.
I always thought that Killer Croc's first app was Detective Comics 523, it was a cameo but still his first appearance.
