Hi, if I am trying to sell a collection of baseball, football, basketball cards, and the amount of cards is about 5000. How do I go about showcasing What it is that I have?

I currently use COLLX and it shows I have about $7500 worth of cards with 3/4 of them uploaded. I realize this is very inaccurate as I have read many threads saying this. So really I do not know if I have $4000 worth of cards, $2000, or $500.

Do I post the top 5, 50, 500? How do I even figure out what the top cards are based on what I have uploaded in COLLX?

Using that program, I can sort my collection by price or a year, team, etc. is it best to link my account in a thread or use some other kind of image platform?

Should I just take out all of the strange, looking ones that have a 3-D-ish effect on them and use those?

What I am definitely trying to avoid doing is surrounding myself with all of these boxes of cards and having to manually input the information and do some computer program or website.

The vast majority of these cards are from 2020 and later. There was a online purchase of about 100 packs from the mid 80s to mid 90s but that is it as far as those dates.

I welcome any suggestions or advice from anyone.

Thanks!
