Challenges of a domain's value?

Excuse me for being a noob. Also, I have some domains for years that I had plans to use, but realize I don't have the time or funds to develop. It was recommended for me to ask on this site. I did try a few bots to evaluate the value and the results don't make sense to me. One said $400 or so. GoDaddy said about $1300. But I see domains on GoDaddy and NameCheap with names kind of like mine go for $30k ~ $250k. I've seen wonky names asking for $500,000 ~ $50 million, which is unrealistic. of course.

I think mine is a good 3-word.com name, easy to spell with 11 letters. Even years ago, I think it got 2000+ monthly visits with a dud site. Today, its about 100 visits a week with no SEO or anything, just sitting there. (Just bots?)

If it's worth about $5k, then I'd be fine with that. But I'd be upset to sell at $5000 if it was worth $30,000 or more, especially 6 figures - which I would find unrealistic. Of course, the right buyer at the right time.

Or are there brokers who are looking for certain domains for clients?
