Good question but totally impossible as registrar's are vultures and will sell your babies on namejet and snapnames
Or their own auction site like godaddy.
Also even if you were able to get them at hand reg that means no one wanted them in the drop market. And mind you thousands of domainers monitor expired lists like vultures too.
If your domains get past them ? Trust me. It's no accident. The domains just suck.
You'd be taking a big risk.
Just keep and monetize simple as that.
Here's a suggestion
Pay for a press release. In that or mention as many of your domains as possible. But make it look "nice".
Then park your domains at either parking crew or bodis or park logic which ever.
The press release with get your domains backlinks on all the major news sites and high rank sites. Good seo.
You should get good traffic then to get clicks hopefully on your parked domains. Enough to cover renewal fees.
You do have 365 days. It would be next to impossible to not make at least $20 a year per domain
If not then you are doing something wrong lol
