Ask HN: How to properly sell a premium domain?

With the introduction of the '.now' top level domain, I bought some domains that i think would be worth a decent amount of money. Instead of just posting them on my registrar's marketplace for some made up sum (my registrar doesn't offer auctions) is there a better way to go about this?

- How can i accurately price them?

- Do i "market" them or will potential buyers just find me?

- Do i just make a "For Sale" holding page with my contact info and wait for someone to reach out?

- Is there some third party that can do all of the above for me?

- etc...

Can someone who has gone through a similar process shed some light on what to look out for?

Thanks!
