In that case, an easy way to get ballpark market values is to use Ebay Sold auctions (Advanced Search). Search for example for "New Mutants 98 CGC 9.0" and you'll see the last 3 months of sales. You can put in a few different grades (including what you think your book is in) and get a rough sense for value and whether you think valuable enough to get graded. 

Thanks that is excellent advice and I will do that.

I think this comes down primarily to 2 things:

- why do you want to slab, is it purely for selling? Or do you also want to keep around (but potentially sell down the road?)

- what grade you think your books are in

For most modern books, except for a few keys (eg. NM98, BA12, NYX3), and rare variants, books only get worth something decent (let’s say >$150) in 9.6 or 9.8, and for many books, only 9.8. 

So a lot of the decision re: “is it worth it” comes down to whether you’re confident it would be a 9.6 or a 9.8 (and at this level, the difference between the 2 grades is pretty hard to spot if you’re not experienced in grading). 

So there’s a lot of factors, but ultra simplified, I’d say minimum value I’d consider (graded) is $100, and if you’re new at graded books, I’d err closer to $150/200, because you’re likely to over-grade your books. 

 

My main goal is to preserve my more valuable issues. I don't have any plans on selling them at least not for another 10-20 years. I have little experience in grading. I was very careful when reading them and making sure they were stored properly. Thanks for the info, it gives me some food for thought. By the way I do happen to have a NM98. I didn't realize what the value had climbed too.

My collection is all modern age comics from the late 80's to early 2000's. They are all bagged, boarded and in boxes. I have an excel file listing titles, quantity and my cost (most of them were bought direct from Westfield Comics) along with a current Overstreet Price guide value. I'm not really interested in selling any at the moment, but am trying to gauge what a good cut-off value would be to have sent in for grading. I realize that it is subjective for each person, so I'm looking to see what others have done in the same situation. For example I have half a dozen that show of value over $100. Would anyone go lower than that, like down to $50 ? Or how about a run of 3-4 issues together that value out over $100 ?

Thanks for taking the time to answer!
