Hi and welcome to NP. I have been following io domains for a while and even bought and sold a few. IMO generic English word are doing well, but it needs to be more tech/startup related. Yours do not fall in this category and I will be surprised if you get more than $50 each.
As for the 3L's. The market is a bit volatile. I have seen 3L's sold for $15 up to $300. personally I have sold ani.io for $190 which was the highest Ive seen in Flippa for a while.
To be fair, I have not listed any io domains on Godaddy or Sedo, so I cannot comment on those.
In general....io domains is used by startup companies if the .com is unavailable. Right now its a bit hit and miss as most people do not realise the true value of io's.
