Tracking Values 1 1

[SellinMyCollection]

All, I have 1000+ comics and want to track the value over time.  I currently am using a spreadsheet but it doesnt update values.  

What do you use ?  App?

You could hyperlink to GPA Analysis?

Are these graded books or raw books?

If they are raw and have had a grade assigned...

Every 6 month's I check eBay Sold Auctions for my top 100 (+) books and keep a log, and have been for 6 years now.

eBay sold auctions are actual FMV since this is exactly what folks are paying for these books.

You need to look at auctions that have a book in the same grade as yours with at least 5 bidders, being sure that there was not a bidding war that artificially raised the price.

IE; Amazing Spider-Man 20 VG/FN 5.0, 2015 value = $105.00, as of June 2021 value = $400.00

For most Super-Hero books you should be able to find numerous past sales for books in your grade, I have a hard time finding actual FMV for my early Westerns and Early Pre-Hero Horror since there are not often for sale through auction, they are usually "Overpriced,(IMO) Buy It Now".

I think he’s looking for a program/website that will automatically update his tables

Aren't we all...

I used this way back in the day. Not sure if it is what you are looking for.

It's pretty customizable if you got the time. Not sure about auto updates for pricing. There was a website i used for that, but it was pretty inaccurate iirc.

 

Found this https://www.collectorz.com/comic/comic-collector/whatsnew/windows/2019/08/01/v19-3-1-new-comic-values-powered-by-gocollect#more-10077

They have really improved this since the last i used it. Lost my old database and need to keep track of my collection again.
