Overstreet Price Guide Golden Age Values

[telerites]

How does Overstreet calculate values - especially on Golden Age books (if that is any different than others)?

I know CGC is not reflected and the multiples of guide on higher graded CGC books. I've seen some online price guides that reflect CGC values and the Comics Buyers Guide has some of the CGC values reflected.

It seems like I read something somewhere that on average golden age books increase by 8% per year in Overstreet's guide. That seems high for an average but key books may bring it up enough and it may not be right at all.

Can anyone help?

I just a quick scan of my spreadsheet - focusing on DC, Fawcett and Nedor superhero books.

I check maybe 25 books in the Very Good to Fine range. The price increase from 2004 to 2005 was from 0% to 5%.

In theory, Overstreet surveys the dealer community for prices but it does seem like there isn't much rhyme or reason behind some increases (or lack thereof).

I can only guess that the 8% increase is for higher grades and that the gap from low/mid to high grade must be growing.

Thanks for the info, Scott. I know Timelys have absolutely sky-rocketed. And key issues from publishers have also done well. I may take a look at some of my GA books and track the change over a few years.

They take existing data and give it an acceptable increase per year. Comics are a sure fire investment - they always go up!
