opinion Short exact-match product domains: how much have you sold for?

I recently registered 2 exact match product domains one 6 letters long(singular) in the pet niche and the other 8 letters long (plural) in the hockey niche. Both with 1-10k monthly searches but some of their LSI keywords have up to 100k searches..

If you’ve sold exact match product domains, how much did you sell for? I know it depends on the niche and amount of end users, but just trying to see if my price estimate is reasonable. Thanks..
