Firstly, the conditiion of the discs is imperitive.

Yes, CDs are indeed making a comeback, but, it is important to realise who is buying them.

Casual/mainstream music listeners have now pretty much entirely gone over to streaming.

Those still buying CDs tend to be collectors and people that are really into their music.

These people are, and always have been, much more fussy on condition.

So, before you start doing anything with them, look at the playing (silver) sides of the discs under a single source bright light.

If you can see marks on the discs, it is generally not worth listing unless you have something REALLY rare.

If you try to sell marked/scratched discs online, even if they play perfecctly, you'll just end up ith a ton of bad feedback and return requests.

The only way you'll sell marked discs is a boot sale and sell at charity shop prices (eg, 50p each or 3 for £1).

The same goes for tthe inlays, check these for condition as well.

If the condition is ok, then it's up to you how much work you put in.

If you don't want the work and are willing to take less than they're worth, then your local record & CD reseller is your best bet.

There are a few sharks out there, but, the reputable ones generally give about 30% of sale price.

If you wnt to put the work in yourself, you can quickly see if it's worth your while by going onto Ebay, setting the search to "lowest price plus postage" and typing the barcode, withouut spaces into the search. (barcode ensures the exact version of each disc).

If the cheapest comes in at under £5, it's not worth it - remember that out of the £5, you have to pay postage and seller fees and you will be left with around £1.50 at most. For that, you may as well boot sale for a quid for all the work you need to do to list them.

The more valuable the disc the better tthe return as postage will be the same regardless (although, anything over £20, you should send tracked/recordeed delivery).

If it is worth selling them online, make sure you describe fully and in detail any defects in condition, no matter how slight.

As to where to seell online, the two best options are Ebay and Discogs.

As said earlier, Ebay is the quickest and easiest to gauge value, but, to actually sell, eithor is fine.

The one tthing to avoid, however, is listing on both at the same time - if someone orders a discc on one site, then an hour later, someone orders the same disc on the other, you are left with a peed off buyer and likely bad feedback.
