it is already worth more in some circles...
It definitely is in my small circle.........
I do think that the SC#22 is a huge DC silver age key, but the SC#4 books seem to be more scarce than the SC#22's.
I don't know if they are more scarce, but the market is not the strongest right now so fewer copies are trading hands. SC #22 was in the same boat just a couple of years ago........
Yeah, I think it was only about 2+ years ago that a SC#22 could be had for around guide (or even less).
I still remember having problems finding a SC22 2 years ago. Once the movie stuff hit the news, it was a lot easier for me to get my SC22.
that's because 3 years ago I started buying up every copy in the market
